Abstract:
Methods and catalyst compositions for oxidizing CO to CO2 at low temperatures arc disclosed. In embodiment, a method of oxidizing CO to CO2 may involve heating a gaseous mixture comprising at least CO and O2 with a catalyst mixture comprising Pd disposed on a Mn3O4mesoporous support at a temperature of about 0° C. to about 60° C., and wherein the CO to CO2 conversion rate is about 40% to about 100%.
