Progress in Homogeneous Catalytic Hydrogenation of CO2

Abstract

In recent years, due to the rising of sustainable development strategies and concerns about global warming, chemists have pay more attention to the application of carbon dioxide (CO2) as a resource for chemical synthesis. Thereinto, in the research of the using of CO2, catalytic hydrogenation of CO2 is one of the momentous means for the utilization of CO2. The homogeneous catalytic reaction has the advantage of mild reaction condition, high activity and easy regulation of the catalytic system and so forth, so the homogeneous catalytic hydrogenation CO2 becomes to be a hot topic in utilization of CO2 resource, especially in the catalytic production of formic acid, formaldehyde, methanol and amine derivatives, it has extensive application prospects. In this paper, the recent progress in the research of homogeneously hydrogenated CO2 catalyzed by organometallic complexes is reviewed. It included that types and structures, activity and selectivity of homogeneous catalysts for the catalytic production of formic acid, formaldehyde, mathanol and as C1 synthons, and the advance in the reaction mechanism of homogeneous catalytic hydrogenation of CO2.
