【摘要】 在 CO氧化过程中贵金属催化剂活性好、寿命长 ,但由于贵金属资源缺乏 ,人们又探讨用非贵金属或少量贵金属来替代贵金属催化剂。其中 ,稀土氧化物在 CO氧化催化剂中的作用越来越引起人们的重视。本文对 CO氧化催化剂的种类和发展现状作了综述更多还原

【Abstract】 Noble metals, as important CO oxidation catalysts, have a good activity and long-life time. With the concern of shortage and high price of noble metals, it is necessary to carry out the studies looking for the substitution of noble metal catalysts. More attention is being paid to the roles of rare earth elements as CO oxidation catalysts. This paper gives a review of present studies on CO oxidation catalysts using noble, non-noble and rare earth metals or their oxides.更多还原
