Studies of Hydrogen Production by the Water Gas Shift Reaction and Related Chemistry
Abstract
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 - PtC12(SnC13)2-(SnC13)2-2, Rh(CO)2C12, Rh(CO)2C12-2, PtC12-4PbC12, and PtC13(C2H4)-. None of these electrocatalytically oxidized CO; however, RhC1(PPh3)3, Rh(dppe)(mnt)-, and Rh(dppe)2+, complexes known to bind CO, did exhibit some limited electrocatalytic CO oxidation behavior.
