Many systems have been investigated for the catalysis of the water gas shift reaction, H2O CO yields H2 CO2, and for electrocatalytic oxidation of CO, CO H2O yields CO2 2H 2e-. These systems have involved precious metal complexes composed of Pt, Rh, and Ir, and reaction conditions for these systems have been especially mild atmospheric pressures and low temperatures 80-100 deg C. In addition aqueous acidic conditions for these systems have been pursued with particular interest in adopting water gas shift catalysts to act as electrocatalysts for the anode reaction of CO fuel cells. Under these conditions the best water gas shift catalysts observed have been PtCl42--SnC14-SnC14-SnC12, trans - PtC12SnC132-SnC132-2, RhCO2C12, RhCO2C12-2, PtC12-4PbC12, and PtC13C2H4-. None of these electrocatalytically oxidized CO however, RhC1PPh33, Rhdppemnt-, and Rhdppe2, complexes known to bind CO, did exhibit some limited electrocatalytic CO oxidation behavior.
