Non-precious metal-catalyzed hydrogenation of CO2

The use of carbon dioxide as raw material for the industry offers several benefits from economical and environmental points of view. Indeed carbon dioxide is an important renewable and abundant source of carbon. Furthermore, it is a nontoxic and almost inexpensive material. Hydrogenation of carbon dioxide (Scheme 4) has proven to be a good method for the use of CO2 as a chemical feedstock. The method has the potential to replace the more toxic carbon monoxide which today is used in industry, due to its high reactivity, for the production of formic acid or alkyl formats. For this purpose, mostly noble metals like ruthenium, rhodium and iridium have been used with high performance. In this regard, we are interested in hydrogenation of CO2 and bicarbonates catalyzed by non-precious metals such as iron.
