Metal-organic frameworks (MOFs) are a unique class of crystalline solids composed of metal cations or cluster and organic ligands that have shown enormous promise for a wide range of applications. Over the past 20 years MOFs have become one of the most intensively and extensively explored material families. As a relatively new type of solid adsorbents, MOFs have demonstrated numerous advantages over some conventional/traditional sorbent systems because of their nearly unlimited tunability in crystal/pore structures and adsorption properties. Among many interesting topics, MOF based gas adsorption and separation have attracted the most attention. This presentation will focus on our recent effort and progress in developing microporous MOFs for selective gas capture and separation in several important separation processes. Our studies show that both the capacity and selectivity of the MOF sorbents can be greatly enhanced by engineering their crystal structure, porosity, chemical composition and surface functionality.
