Combustion of fuels liberates CO2 and H2O. The thermodynamic stability and kinetic inertness of these molecules makes their conversion into useful chemicals quite challenging. However, the ability to convert these molecules to useful materials and fuels would be advantageous to modern day society both because they are quite abundant on earth, and because CO2 is a known pollutant. Under proper electrochemical conditions, water can be oxidized to O2, protons, and electrons, and CO2 can be converted to CO using the liberated protons and electrons. CO is a feedstock for many chemical processes, and is thus an attractive target molecule for generation from CO2. Here, we will discuss synthesis and characterization of monometallic and bimetallic compounds that could potentially serve as catalysts for CO2 reduction, proton reduction, or water oxidation. The compounds are supported in part by the ligand dimethylglyoxime and its derivatives, as these are cheap and can support a variety of redox-active metal complexes. We will discuss our latest results, including solid-state structural data obtained from X-ray diffraction studies on novel heterobimetallic complexes.
