Cu-Mn/Al2O3, Cu-Mn/TiO2and Cu-Mn/SBA-15 were prepared by incipient wetness impregnation. The activity of those catalysts for selective catalytic oxidation (SCO) of ammonia to nitrogen at low temperature (100°C~250°C) is not so satisfying. 5%Cu-5%Zr/TiO2has the highest NH3conversion and highest NO, NO2yield. 5%Cu-5%Mn/Al2O3is a promising NH3selective catalytic oxidation catalyst, but still needs further study. SBA-15 is a bad support for Cu-Mn. Al2O3-based catalysts and TiO2-based catalysts were also prepared by incipient wetness impregnation to sure the synergistic effect between transition metal. The results find the activity on Cu-Mn/Al2O3is better than Cu-Mn/TiO2, but NH3conversion on Cu-Zr/TiO2is rather well with high yield of NO. The role of supports and transition metals play in catalyst are discussed by a series of experiments. Key ward: SCO, NH3, transition metal, γ-Al2O3, TiO2, SBA-15
