摘要：
Ni(0.4)-MnOx catalyst was prepared by citrate combustion, which showed high catalytic performance for NH3-SCR reaction. After the resistance tests of SO2 and H2O, Ni(0.4)-MnOx-SH showed better NH3-SCR activity than that of Ni(0.4)-MnOx, when the temperature was >240 degrees C. The characterizations suggest that Ni(0.4)-MnOx-SH has more acid sites for ammonia adsorption and far weaker oxidation capacity for NH3, which resulted in the high catalytic activity at middle-temperature.
