摘　　要：催化消除CO主要包括CO的完全氧化(CO-COOX)和优先氧化(CO-PROX).首先,结合本课题组的相关研究,按照催化剂体系介绍了Cu基催化剂在CO-COOX中的活性物种和组分之间的相互作用.其次,对用于富氢气氛下CO-PROX的Cu基催化剂进行了系统的分类总结,重点阐述了CuO-CeO2催化剂的制备方法、助剂改性、载体调变以及过渡金属离子掺杂(CuO/Ce1-xMxO2)、反相结构(CeO2/CuO)等方面对CO-PROX催化性能的影响.最后,总结了Cu基催化剂在CO-PROX中存在的问题,并展望了未来的研究趋势.Catalytic elimination of CO mainly includes complete oxidation （CO-COOX） and preferential oxidation of CO （CO-PROX）. First, combined with our group＇s research, a brief introduction to the active species and the interaction between components in Cu-based catalysts for CO-COOX was presented from the perspective of the catalyst system. Then recent progress in CO-PROX under H2-rich over Cu-based catalysts was systematically summarized. Influence of the preparation method, promoter, and support of CuO-CeO2 catalyst as well as transi- tion metal ions doped support （CuO/Cel_xMxO2）, and inverse structure （CeOJCuO） on the catalytic performance in CO-PROX was elabo- rated. Finally, the application problems and future research trend of Cu-based catalysts for catalytic removal of CO were discussed and sum- marized.
