Abstract
Possible homogeneous catalysts were synthesized, tested, and screened for their CO2 reduction potential. The potential catalysts were synthesized with the Hamilton Starlet automatic pipetter, which combined solutions of metal salts and ligands together directly into a twenty-five well electrochemical cell. The cell , which incorporates printed metal electrodes into a teflon well block, was then used to perform bulk electrolysis. CO2 reduction was first identified through gas chromatography of the head gas collected after bulk electrolysis, which showed the presence of CO, the reduced species. Since CO2 reduction is typically accompanied by proton consumption, catalyst activity was further confirmed by a pH test.
