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 catalysis using rhodium and ruthenium complexes. In recent years there has been a growing concern to design catalysts that are able to convert carbon dioxide to C1 products. Several approaches such as electrochemical and photochemical reduction of carbon dioxide using metal complexes has been studied. Results from these studies indicate that metal complexes 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 metal complexes in catalytic hydrogenation of carbon dioxide.
