摘　　要：汽车冷启动时催化剂床层温度低,尾气中的CO和烃类不能被传统三效催化剂有效消除。目前,非贵金属类的过渡金属氧化物催化剂用于CO和烃类的低温氧化受到了广泛关注。本文综述了近几年来国内外以Cu、Co和Mn的氧化物为主要代表的过渡金属氧化物上烃类和CO氧化的研究进展,对催化剂上界面氧空位参与氧化过程的反应机理进行了总结,展望了过渡金属氧化物催化剂用于CO和烃类低温氧化的未来研究趋势。The conventional three-way catalysts are not efficient enough to remove the CO and hydrocarbons during vehicle cold-start period due to the low temperature of catalyst bed.Recently,transition-metal oxide catalysts used for oxidation of CO and hydrocarbons at low temperature have attracted much attention.The main advances in oxidation of CO and hydrocarbons on transition metal oxide catalysts during the past several years are systematically reviewed,mainly on the Cu,Co and Mn based oxides which possess good oxidation performance.The reaction mechanism involving interface oxygen vacancy on the catalyst participated in the oxidation reaction is summarized.The research tendency of transition-metal oxide catalysts used for low-temperature oxidation of CO and hydrocarbons is proposed.
