Carbon monoxide can be oxidized by oxygen gas or other oxidants catalyzed by nickel cyano carbonyls in basic solution at ambient temperature. A prototype CO-powered fuel cell was constructed based on this nickel cyano carbonyl catalyzed oxidation. In the presence of polymeric CO-coordinating double metal cyanides (M(H2O)2Fe(CN)4(CO)2 (M = Mn, Fe, Co and Cu), ZnFe(CN)4(CO)2, Fe2[Fe(CN)4(CO)2]3 and FeFe(CN)5(CO)), carbon monoxide can be activated by heat to undergo a series of interesting reactions. CO reacted with nitrogen oxides to produce CO2 and N2 at 200 – 350oC under 1 atm pressure. CO also reacted with water vapor to produce CO2 at the same condition.
