Progress in selective catalytic reduction of NO_x with hydrocarbons under lean-burn conditions——Meta

摘要: 综述了负载或非负载的金属氧化物催化剂体系上,富氧条件下NO的非选择性催化还原反应性能及反应机理着重讨论了还原剂种类、催化剂结构与化学性质对催化反应的影响及催化剂的耐水性和耐SO2性能探讨并总结了金属氧化物催化剂体系上NO的还原机理

Abstract: The oxides/base metal catalysts in selectwe catalytic reduction(SCR) of lean-NO_x is reviewed, emphasized on the influence of structural and chemical features of catalysts and reducing agent on catalytic activity, and the water- and sulphur-tolerance of catalysts. The lean-deNO_x reaction mechanism over oxides is summarized.
