Comparing with the activity of NiO/γ-Al_2O_3, NiO/TiO_2, and NiO/CeO_2catalysts, NiO/CeO_2 showed the highest light-off conversions of NO and CO and lowesttemperature of total conversion. Three kind of CeO_2 prepared by homogeneousprecipitation, precipitation, and direct decomposition method wereused as the carrier of NiO. Through the activity comparison of NiO/CeO_2, NiO/CeO_2and NiO/CeO_2, CeO_2 optimized as the preferable carrier for active component at aspace velocity of 120 000h~(-1, the coversion of NO is 50％at 170℃over NiO/CeO_2catalyst, and the complete conversion of NO and CO occurred at 210℃.
