英文摘要	pt single atoms and small clusters were dispersed on iron oxides by a facile coprecipitation method. these catalysts, with or without calcination at elevated temperatures, show excellent activity and selectivity for preferential oxidation of co in the h-2-rich gas. they can completely remove co from h-2-rich gas at a wide temperature range of 20-70 degrees c, which renders them suitable for low-temperature applications. the reaction followed a mixture of competitive mechanism and a noncompetitive/redox mechanism. the weakened co adsorption on small pt clusters and atoms makes the competitive adsorption of o-2 feasible, which ensures a high activity of pt/fe catalysts, even calcined at elevated temperature.
