One approach to the conversion of carbon dioxide into a more valuable chemical commodity is through its electrocatalytic reduction. Previously it has been shown that a series of palladium compounds supported by triphosophine ligands were effective electrocatalysts for the reduction of CO 2 to CO. In addition, a bimetallic catalyst that incorporated two [Pd(triphosphine)(solvent)] 2+ units was found to very selectively reduce CO 2 to CO at rates comparable to the [NiFe] CO dehydrogenase enzyme, but suffered from very short catalyst lifetimes. The work to be presented includes several ligand modifications as well as the preparation of analogous nickel complexes in order to further probe structure-activity relationships among this class of catalysts. Novel bimetallic catalysts intended to mimic the cooperative chemistry of the [NiFe] CO dehydrognenase have been prepared and characterized, and their electrocatalytic performance for the reduction of CO 2 will be discussed.
