摘要:
Selective reduction of nitric oxide in pressence of oxygen is one of the major challenges in the automobile exhaust after-treatment for lean-bum gasoline engines and diesel engines. Besides Cu-ZSM-5, Pt and Pd based noble metal catalysts, alumina-supported silver catalysts show high activities on NOx conversion to nitrogen[1,2]. However, NO conversion activities over silver on binary oxides have rarely been studied in detail[3], although copper on SiO2-Al2O3 catalyst was reported to have a high activity[4] Here, NOx reduction activities on SiO2-Al2O3-supported transition metal catalysts prepared by sol-gel method was investigated.
