摘要：

The promoting effect of supported metals on alumina catalyst was investigated for the reduction of nitrogen monoxide in oxygen-rich atmospheres. For NO reduction with propene over impregnated CoO/Al2O3, the first reaction step was found to be the oxidation of NO to NO2 probably catalyzed by dispersed cobalt species. The next reaction step, which is the reaction of NO2 with propene to form N-2, was considered to take place on the alumina surface. Although the activity of impregnated FeO/Al2O3 was low because of the presence of large iron oxide particles catalyzing propene oxidation with dioxygen, FeO/Al2O3 prepared with sol-gel method showed excellent deNO(x) activity.
