摘　　要：文章概述了目前使用的CO低温氧化催化剂存在的缺点,分析了贵金属,非贵金属催化剂的研究进展和稀土助剂在此类催化剂中的应用,指出了今后开发此类催化剂的方向包括降低贵金属用量,改善传统催化剂在高湿度条件下的使用寿命和抗中毒同时应加大稀土类催化剂的开发力度。Defects of commercial catalyst for low-temperature CO oxidation were analyzed in the paper. Latest research development of both noble and non-noble catalysts as well as application of rare earth elements as assistants were also reviewed. Future research trends include decrease of noble elements usage in catalyst preparation, increase of service life and anti-poison ability of nowadays commercial catalyst under high humidity condition and emphasis on development of rare-earth catalysts.
