摘　　要：CO氧化反应是控制汽车尾气污染和理论研究的重要课题之一。贵金属催化剂活性好,寿命长,但由于资源缺乏,价格上涨,人们一直研究用非贵金属或少量贵金属来替代贵金属催化剂。稀土在CO氧化催化剂中的作用越来越引起人们的重视。介绍了贵金属、非贵金属和稀土催化剂。The oxidation of CO plays important roles in control of automotive emission and theoretical research. Noble metals, as CO oxidation catalysts, have good activity and long service life. But with the deficiency of noble metal resources and the escalation of their price, it is necessary to search for alternatives for noble metal catalysts. More attention is being paid to the roles of rare earth in CO oxidation catalysts. Noble metals, nonnoble metals and rareearth catalysts were reviewed in this article.
