Metal-organic frameworks as catalyst precursors in Catalytic Hydrogenation of Carbon Dioxide: Review

Abstract

Catalytic hydrogenation of carbon dioxide to value-added chemicals is an attractive process to address both energy and environmental issues. Several approaches have been used to convert the greenhouse gas to useful products. This conversion has been done mainly through homogeneous catalytic systems of platinum group metal complexes. In recent years there has been a growing concern to design heterogeneous catalysts that are able to convert carbon dioxide to C1 products. The large surface area that metal-organic frameworks coupled with porosity make them better candidates for catalytic conversion of carbon dioxide to the desired products. Results from these studies indicate that metal-organic frameworks (MOFs) may answer both environmental and energy issues associated with the production of the greenhouse gas. This contribution will focus on the recent development in the design and application of MOFs in catalytic hydrogenation of carbon dioxide. Special emphases on tandem capture of carbon dioxide and hydrogen followed by subsequent hydrogenation of carbon dioxide in the presence of frustrated Lewis pairs functionalised MOF will be discussed.
