Reticular Chemistry: Molecular Precision in Infinite 2D and 3D

Reticular chemistry is concerned with linking of molecular building blocks with strong bonds into extended structures. This has resulted in metal-organic frameworks and covalent organic frameworks. The chemistry of these frameworks and their application to harvesting water from desert air among other applications will be presented.

MOFs for Energy Intensive Separations: Moving Beyond the Lab

Metal-organic frameworks (MOFs) have been at the forefront of research activity for almost two decades now. In the present work, we developed various MOFs that can carry out many energy-intensive separations either by a periodic arrangement of requisite functionalities in the channels for optimal host-guest interactions or by tuning the aperture size of the channel window to afford size-selective separations. We were able to achieve many industrially important separations like CO2 capture, olefin/paraffin separation, branched/linear paraffin separation and natural gas upgrading. Molecular-level Insight was obtained for a better understanding of the separation processes. In collaboration with industrial partners, some of the MOFs with exceptional performance will be investigated in a real like conditions at demonstration scale for taking them to the next level. Economical and rapid scale-up methods for these materials are being developed and we have successfully produced these materials in kg quantities.

MOFs in Mixed Matrix Membrane for Energy Intensive Separation: Impact of Surface Engineering and Morphology

Membrane-based separation is a promising alternative to conventional processes such as cryogenic distillation and/or adsorption based separation. Among the existing membranes for gas separation, polymeric membranes and inorganic membranes have been immensely studied, but each type has its own pros and cons. Therefore, current situation demands the development of mixed matrix membranes (MMMs) by incorporating molecular sieve fillers into the polymer matrix, which provides a decent strategy to combine the merits of each material and fabricate novel hybrid membranes with superior gas separation performance. Metal-organic frameworks (MOFs) have been proposed as novel molecular sieve fillers owing to their unique pore structure and chemical variability. MMMs fabricated using MOFs fillers was supposed to outperform other porous fillers, but due to the limitation in separation performance of the filler within and challenges concerning the compatibility between MOF filler and polymer interface structure, only a small fraction of the works reported both improved permeability and selectivity simultaneously. In this presentation, we will show our research focused on enhancing the compatibility of the MOF filler and polymer matrix by judiciously modifying the MOF’s surface chemistry, and exploring how morphology, particle size and particle distribution drastically influence gas separation performance.

Merging scientific curiosity and engineering approaches to solve gas separations challenges

Using examples from our recent work, I will present two approaches used by our group to develop porous materials to be applied in a variety of separation applications. The first one is a curiosity-driven approach, which we employ either for new separation challenges for which benchmark and/or performance targets are ill-defined or in the context of emerging adsorbent materials. I will illustrate this aspect through our recent findings on porous boron nitride. Our second approach, based on molecular engineering, accelerates materials development for well-defined applications. Such approach links molecular modelling, experiments and process modelling to quickly identify the best adsorbent(s) for a given separation. In this context, I will present our work on the use of metal organic frameworks for industrially relevant gas separations.

Porous materials and rotation about single bonds

One of the distinguishing features of metal-organic frameworks and other non-traditional porous materials, such as interlocked cage molecules, is their ability to respond flexibly to changes in their environment by changing their structures. There are a variety of mechanisms for this, including the relative displacement of two rigid networks and the repositioning of a linker with respect to an inorganic building unit. We have concentrated on rotations about single bonds in organic linkers as a route to change structures that has some similarities with the restructuring mechanisms adopted by biological molecules. This presentation will both review progress and cover recent results that include a new system that adopts multiple distinct crystal structures by this single bond rotation mechanism.(1)
Materials dynamics, including single bond rotations of this type, are important for separations. I will discuss high-throughput computational approaches to identifying candidate materials.

Two-dimensional membranes for carbon capture: role of material chemistry and engineering

Two-dimensional materials have risen in popularity as a desired material for membrane in the last decade. Nanoporous single-layer graphene, prepared by incorporating subnanometer vacancy defects in the graphene lattice, is highly promising for high flux gas separation because the resistance to diffuse is controlled by a single transition state at the nanopore [1–3]. Molecular sieving resolution (MSR), defined as the difference in the kinetic diameters of molecules to be separated, of a fraction of an angstrom has been predicted, allowing separation of industrially-relevant mixtures such as CO2/N2, CO2/CH4, O2/N2, etc, allowing graphene-based membranes to compete with those from zeolites and carbon molecular sieves. However, the realization of single-layer graphene membranes for gas separation has been hampered because of the difficulty in controlling the nucleation and growth of vacancy defects in graphene.

In this presentation, I will share development in my laboratory on the synthesis of high-quality gas-sieving graphene membranes focusing on the aspects of creation of vacancy defects and their versatile functionalization potential [4–7]. I will discuss the factors that control intrinsic vacancy defects, which are incorporated in graphene lattice during the synthesis of graphene, and the role of such defects in gas separation using 1 mm2 sized membranes. Further, I will discuss a novel graphene gasification chemistry leading to a high density of nanopores with a narrow pore-size-distribution enabling gas sieving with MSR of 0.2 Å [8]. In the context of carbon capture, record high separation performance could be obtained. I will show that molecular cut off size can be tuned by a fraction of Å with either reduction in pore size by functionalizing nanopore edge or expansion of pore size by etching [8].

Finally, I will discuss scale-up of single-layer graphene membranes for gas separation discussing our recent unpublished results where centimetre-scale membranes were fabricated yielding attractive gas-sieving performance under pressurized conditions [8].

Designing Responsive Membranes

Modification of membrane surfaces by grafting polymer brushes from the surface has been shown to impart unique surface properties. Here we focus on magnetically responsive membranes where magnetically responsive polymer chains are grown from the membrane surface. We have developed a range of microfiltration1, ultrafiltration2 and nanofiltration3 membranes by grafting magnetically responsive polymer brushes from the membrane surface.
Atom transfer radical polymerization (ATRP) has been used to graft poly-hydroxyethyl methacrylate (polyHEMA) from the surface of the membrane. Superparamagnetic nanoparticles have been attached to the chain ends. In an oscillating magnetic field, movement of the magnetically responsive nanobrushes leads to suppression of concentration polarization resulting in higher permeate fluxes and better rejection. We have also grafted poly(N-isopropylacrylamide) a thermo-responsive polymer that exhibits a lower critical solution temperature, using ATRP, from the surface of the membrane4. By carefully choosing the frequency of the oscillating magnetic field, movement of the polymer chains can induce mixing. Using much higher frequencies, around 1,000 Hz, heating will lead to collapse of poly(N-isopropylacrylamide) layer as the temperature of the grafted polymer layer increase above the lower critical solution temperature of the grafted poly(N-isopropylacrylamide).

Unlike nanofiltration and microfiltration membranes where the majority the polymer chains are grafted from the barrier layer or the inside pore surface respectively, in the case of ultrafiltration membranes significant grafting can occur from both the barrier layer and the internal pore surface. In addition, given the smaller pore sizes compared to microfiltration membranes, pore plugging by the grafted polymer chains must be avoided. We have developed a novel technique to selectively graft from the external barrier layer and not the internal membrane pore surface. We show that the magnetically responsive polymer brushes can have a significantly different effect on rejection and flux of model feed streams consisting of proteins such as bovine serum albumin, depending on their location on the membrane barrier layer or in the pores. Our work highlights the importance of being able to control not only the three-dimensional structure of the grafted polymers but also their location; from the membrane barrier layer or from the inside pore surface.

Dynamic Structures and Properties of Porous Coordination Polymers / Metal-Organic Frameworks

With the Industrial Revolution in the 19th century, humans began to create technologies that consumed huge amounts of energy. Initially, people used coal (solid) as an energy resource, but the 20th century ushered in the era of petroleum (liquid). In the 21th century, where the depletion of petroleum has become a concern, gases (e.g., natural gas and biogas) should play important roles. Hence, the trend has been shifting from solid to liquid to gas. In the future, an “era of gas” should be realized [1.2]. The recent advent of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) as new functional microporous materials, have attracted the attention of chemists and physicists due to highly efficient capacity of storage, separation and conversion of gaseous substances. Among them, soft porous properties [3] of PCPs are essential for low-energy separation of gas resources, flue gases, air, pollutant gases and other industrial materials[4,5]. We could also develop several approaches to utilize PCPs for catalysts for CO” fixation [7].

Recognition, Sensing and Transport of Anions using Peptides and Peptidomimetics

The selective recognition of anions has numerous applications in areas as diverse as the environment and medicine. Most of these applications require anion recognition to occur in a competitive aqueous environment, but the design of receptors capable of selective binding to anions in water is difficult, predominantly as a result of the high hydration energy of anionic species.
In natural systems, highly efficient and selective anion recognition is achieved through the construction of large peptides/proteins that take advantage of the numerous H-bonding interactions available from various amino acids with additional contributions from NH groups along the protein backbone. This has inspired research into the development of synthetic anion receptors that combine both natural and non-natural binding motifs. We present here novel anion receptors based on macrocyclic and linear peptidic and peptidomimetic scaffolds, that are capable of selective anion recognition, sensing, extraction or transport.

Functionalized ultramicroporous polymers for industrial gas separation applications

Membrane-based gas separation is a rapidly emerging technology that has been well established for the purification hydrogen streams, nitrogen production from air and is showing an increasingly larger roles in natural gas sweetening and vapor/gas separations. One actively pursued strategy to generate new polymeric membrane materials with combinations of high permeability and high selectivity is the introduction of a bimodal distribution of microporosity (pores < 20 Å) and ultramicroporosity (pores < 7 Å) in the polymer matrix. It has been shown that rigid ladder-type chains comprising fused rings joined by sites of contortion pack inefficiently in the solid state to produce polymers of intrinsic microporosity (PIMs). Furthermore, the successful integration of monomers contorted by spirobisindane, ethanoanthracene, Tröger’s base and triptycene moieties into polyimide structures has generated highly permeable intrinsically microporous polyimides (PIM-PIs). Some of these PIMs and PIM-PIs exhibited significantly enhanced performance for O2/N2, H2/N2, H2/CH4 and CO2/CH4 separations with properties located on the most recent permeability/selectivity upper bounds.1,2
Several series of PIM-PIs will be presented based on rigid and bicyclic moieties, which are solution processable to form mechanically robust films with high internal surface areas (up to 1000 m2 g-1). Gas permeation and physisorption data indicate the development of ultramicroporous structures that are tunable for different gas separation applications. Specific emphasis will be placed on the potential use of hydroxyl- and carboxyl-functionalized PIM-PIs for energy demanding applications for natural gas treatment and olefin/paraffin separation. PIM-PIs with highly polar functional groups define the recently proposed 2018 mixed-gas polymer upper bound for CO2/CH4 separation.3 The potential use of PIM-PIs as matrix materials for hybrid polymer/MOF and microporous carbons will be demonstrated.

Hyper-cross-linked nano-scale hybrid films

We present a range of tailored inorganic-organic and bio-organic thin film hybrid membranes, as well as the in-situ characterization of these membranes by spectroscopic ellipsometry. The membranes are made by facile interfacial polymerization of an inorganic polyhedral oligomeric silsesquioxane (POSS), or a biological molecule, with an organic bridging molecule. The polymerization reaction results in a thin film giant network. The bio-organic membranes are shown to have a persisting biological functionality. The inorganic-organic hybrids are shown to allow unprecedented molecular separation under demanding conditions, such as high pressure, high temperature, and in the presence of chemically aggressive fluids. In this lecture, particular focus will be on the sieving of hot gases, where membrane separation is a potential key enabling technique for many large-scale chemical processes and advanced energy production technology. The persistence of the selectivity of our new hybrid membranes underlines the hyper-cross-linked periodic network characteristics of the covalently bridged rigid POSS. The facile synthesis via interfacial polymerization allows for tailored spacing of the network by varying the length of the imide bridge. As such, our method allows for production of tailor-made membranes, bridging the gap between the membrane and application requirements.

Nanoporous Materials Genome in Action

The attractive feature of Metal Organic Frameworks (MOFs) is that by changing the ligand and/or metal, they can be chemically tuned to perform optimally for a given application. This unique chemical tunability allows us to tailor-make materials that are optimal for a given application. The promise of finding just the right material seems remote however: because of practical limitations we can only ever synthesize, characterize, and test a tiny fraction of all possible materials. To take full advantage of this development, therefore, we need to develop alternative techniques, collectively referred to as Materials Genomics, to rapidly screen large numbers of materials and obtain fundamental insights into the chemical nature of the ideal material for a given application.

These computational materials genomics initiatives have been so successful that we have created a new problem: what to do with so much data? In this presentation we will discuss different computational strategies to deal with a large amount of data. We illustrate on the use of these strategies by addressing the following questions: How the find the best material for a given application? How to find materials with similar pore shape? How to design a material that optimally binds CO2? And, what can we learn from failed experiments?

Computational Assisted Design of Advanced Adsorbents and Mixed Matrix Membranes

A combination of quantum-and force field-based molecular simulation tools has been deployed over the last few years to assist the experimental effort towards the discovery of novel MOFs with outstanding adsorption/separation performances. This presentation will provide a few illustrations of MOFs that this strong experimental-computational interplay identified as optimal adsorbents for highly challenging energy and environmental adsorption and separation processes (H2O heat transfer, CO2 capture, Natural gas purification….). There is actually a need to develop optimized Mixed Matrix Membranes (MMMs) based on highly engineered MOFs and polymers to combine the best of both worlds. Our group developed an innovative computational toolbox to construct and characterize the MOF/polymer composites at the atomistic scale. This offers a unique opportunity to anticipate the most compatible components that drives the feasibility and stability of the MMMs without the need to experimentally scan the multiple combinations of possible pairs (MOFs/polymers) which is time consuming and impossible to be achieved in an equitable time. This presentation will deliver a series of examples of anticipated highly compatible MOF/polymer pairs that were further experimentally combined into non-defective MMMs and tested for energy-efficient separations.

Nano-Hybrid Thin Film Composite Carbon Molecular Sieve Membranes Based on a Polymer of Intrinsic Microporosity

Carbon molecular sieve (CMS) membranes promise to deliver outstanding molecular separation properties combined with a high chemical and plasticization resistance unmatched by currently deployed polymeric materials. The main challenge, however, remains in transforming them into practical thin-film composites with high enough permeances while simultaneously avoiding the development of defects and preventing substantial mass transport resistance increase due to physical aging. Recently, new opportunities in the fabrication of CMS membranes arose together with the synthesis of polyimides of intrinsic microporosity (PIM-PI) which can be used as precursors to obtain ultra-selective CMS membranes. Crucially, PIM-PIs themselves structurally resemble CMS in terms of their large microporosity and size distribution.

In this work, we describe fabrication of thin-film composite CMS membranes with a particular emphasis on the differences in the film-forming and pyrolysis-related morphological transformations between the more traditional glassy polymers and PIM-PIs. Confinement to the substrate is shown to result in a significant internal orientation of the graphene-like strands and has consequences on the gas transport properties of the obtained composites.

In addition, we introduce nano-hybrid carbon molecular sieve membranes fabricated by pyrolyzing a PIM-PI precursor modified by vapor phase infiltration (VPI). In the process of VPI a metalorganic precursor, trimethylaluminum (TMA) first diffuses into the high free volume matrix of the PIM-PI to form a complex with its functional (carbonyl) groups. Afterwards, water vapor selectively and locally oxidizes the TMA forming nano-dispersed Al2O3 within the polymer matrix. Subsequent inert-atmosphere pyrolysis leads to the formation of Al2O3-doped thin film composite CMS membranes with excellent molecular separation properties positioned in the vicinity or above the polymeric upper bounds for a number of technologically important gas pairs, e.g. CO2/CH4, O2/N2, and H2/N2. In addition, we show that the nano-hybrid CMS membranes possess a distinct physical aging signature that may lead to a significant improvement of the long-term performance.

Porous Liquids and Solvent-free Synthesis

Two topics will be presented:

Porous Liquids: Porous Liquids (PLs) are liquids that contain permanent, well-defined, empty cavities of molecular dimensions.[1] Unlike conventional solvents, they are able to dissolve very large amounts of gas in a size- and shape-selective manner. The advent of this new type of liquid presents opportunities to rethink and re-engineer processes such as gas separations (natural gas or biogas sweetening, ethane-ethene separation etc.) to improve efficiency and sustainability. A case study on more efficient biogas purification will be included.

Solvent-free Synthesis: Solvents are used ubiquitously for chemical processes on large scales but are often costly, hazardous, require energy to purify, can deplete fossil resources and create waste. Looking forward, instead of asking ‘Which solvents should we use?’, we should now be asking ‘Do we need solvents at all?’ Mechanochemistry, in which reactions between solids are induced by means such as grinding, provides a way to perform various types of synthesis, with minimal or even no solvent being used. Recently, we have shown how mechanochemical synthesis can be scaled up and made continuous through the application of Twin Screw Extrusion techniques.[2] The opportunities now presented for fundamentally new science as well as more sustainable production processes will be discussed.

Electrical energy storage with bipolar membrane

Energy storage technology from fluctuating wind and solar sources is the basic prerequisite for transformation of the on fossile energy based system to a renewable energy based one with electricity being the main source for energy consumption. For direct storage of electrical energy large battery systems are being developped based on metals as Li, Co, Mn and V in their various oxidation states. The availability of these metals is restricted due to uncertainty in supply and price development and therefore could limit the market growth needed for customers‘ demand.
In this presentation an electrochemical storage device (Fig.1) is shown in which the charging is done by water-splitting of aqueous salt solution with a bipolar membrane producing acid and base and discharging is done by the recombination of H+ and OH- in the bipolar membrane thus without metal(ion) redox reactions.
Charging and discharging curves with 3 different commercially available bipolar membrane and a self-made one have been tested on a lab-scale unit. In charging three of the membranes showed good performance data, comparable to acid and base production published before. For 1M acid and base concentration an OCP of 0.82V has been measured. In discharging these membranes showed relatively small current densities of around 2-3 mA/cm2 under flow regime.

Circular Carbon Economy - A Holistic Approach to Carbon Management

A circular carbon economy framework for addressing the climate challenge is presented in which a more comprehensive approach needs to be considered where both new energy sources and existing sources contribute in parallel and leverage the existing infrastructure in a way that reduces net carbon emissions in a most cost effective manner. The concept of a circular carbon economy offers a new way of approaching climate goals that values all options and encourages all efforts to mitigate carbon dioxide emissions. This presentation highlights some of the key R&D efforts Saudi Aramco is pursuing in the area of carbon capture, utilization and storage that paves the way towards closing the carbon cycle.

Enhancing the Performance of Desulfation Membranes using aPermanent Coating

Desulfation of seawater before injection is used to control reservoir souring and scale formation. In Sulfate Removal Units (SRUs), nanofiltration membranes are used for this task. A major operational challenge for SRUs is the tendency of the membranes to foul. To overcome fouling, frequent chemical cleaning is required, which leads to excessive downtime and the risk of not meeting water injection targets. Using chlorine as alternative to expensive chemicals for clean-in-place (CIP) is not possible as it degrades the polyamide membrane.
Enhancing the injection water production of the SRU without increasing transmembrane pressure or the number of membranes in the SRU is also economically favorable. Generally, the amount of treated water cannot be increased easily, however, as a higher water output results in a higher fouling rate fouling of the membranes.
In this paper, we describe a method to enhance permeate flux, chlorine tolerance and fouling resistance of desulfation membranes. The enhancements are achieved by modifying the active layer of the membrane using a permanent, proprietary coating that increases hydrophilicity and increased resistance to free chlorine while retaining the high surface charge characteristic of NF membranes. The coating can be applied to any commercially available NF membrane.

Transferring Advanced Materials to Membrane Products: An Industrial Perspective

Membrane separation emerges from a close coordination between material science and process engineering. In membrane gas separation, high selectivity can reduce losses of valuable products whereas high permeability can reduce compression to achieve equivalent output. Superior membrane products originate from superior material intrinsic properties. This is where competencies of a specialty chemicals company, i.e. Evonik, can contribute to unique membrane solutions for the market.
The maximum performance of membrane materials can only be realized when combined with optimized membrane formation, module construction and process design. Polyimide is currently one of the best state-of-the-art polymeric material. Our successful transfer of P84 polyimide into membrane modules, SEPURAN® has established in total more than 300 references in various applications. These include carbon dioxide removal, air separation, hydrogen recovery, helium upgrading and recovery, etc.
Energy efficiency and increasingly stringent emission regulations will continue to be the key drive for new technologies. Furthermore, the integration of advanced materials into membrane products can broaden the applications of membrane in gas separation, e.g. oxygen enrichment and nitrogen/methane adjustment. Technical difficulties and optimisation of total cost of ownership for end-users will remain as key challenges to transfer advanced materials to membrane products.
