In this project, three classes of crystalline porous solids, metal-organic frameworks (MOFs), covalent-organic frameworks (COFs), and zeolitic imidazolate frameworks (ZIFs), will be designed and synthesized to develop solutions for challenges in renewable and cleaner energy. These materials are energy efficient nanoporous solids with ultra-high surface areas (10,000 m2/g) with multivariate functionality into which a large number of functional groups can be incorporated and used for binding gases molecules. These innovative materials will be used for advanced applications, such as carbon capturedfrom flue gas, storage and transport of hydrogen and methane, and catalytic conversion of natural gas to liquids. These materials provide significant advantages over the state of the art materials. Our target is to provide prototype products of crystalline nanomaterials in accordance with our projects. The current projects provide unique capabilities of innovative research in the synthesis, characterization and study of porous nanomaterials and catalysts for renewable and cleaner energy applications.
