Homogeneous Catalytic Hydrogenation of CO2 to Methanol - Improvements with Tailored Ligands

Improved molecularly-defined cobalt catalysts for the hydrogenation of carbon dioxide to methanol have been developed. A key factor for increased productivity (up to twofold compared to previous state-of-the-art-system) is the specific nature of substituents on the triphos ligand. In addition, the effect of metal precursors, and variations of additives have been investigated.
