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℃.

由Al_2O_3、TiO_2、CeO_2负载的NiO催化剂在NO-CO反应中的活性比较得出:NiO/CeO_2催化剂具有最好催化活性;分别采用直接分解法、氨水沉淀法和均匀沉淀法制备了载体CeO_2、CeO_2、CeO_2,并比较了NiO/CeO_2、NiO/CeO_2、NiO/CeO_2的活性差异,得出了以尿素作为沉淀剂的均匀沉淀法制备的CeO_2负载的NiO活性最好空速为120 000 h~(-1的条件下,170℃时,NO的转化率为50%;210℃时,NO和CO的转化率均达到了100%。
