摘      要：The Au/oxide catalysts, in which the oxides are one or both of Fe2O3, NiO, Co3O4, TiO2, Al2O3, Al2O3-SiO2, were prepared by co-precipitation, organo-metal-complex grafting or deposition-precipitation methods. The catalytic performance for CO low-temperature oxidation and NO selective catalytic reduction (SCR) over these catalysts was evaluated and the effects of preparation methods and conditions on the catalytic activities and the structures were investigated by means of TPSR, TPDMS,TEM, XPS, DTA-TG, XRD. It was found that the catalyst for CO oxidation could be used in breathing apparatus instead of Hopcalite catalysts used at present and that for NO SCR with propylene have a good activity at 325-400℃.
