Abstract:
Methods and catalyst compositions for oxidizing CO to CO 2 at low temperatures are disclosed. In one embodiment, a method of oxidizing CO to CO 2 may involve heating a gaseous mixture comprising at least CO and O 2 with a catalyst mixture comprising Pd disposed on a Mn 3 O 4 mesoporous support at a temperature of about 0 °C to about 60 °C, and wherein the CO to CO 2 conversion rate is about 40% to about 100%.
