Abstract: 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 transition metal ions doped support (CuO/Ce1-xMxO2), and inverse structure (CeO2/CuO) on the catalytic performance in CO-PROX was elaborated. Finally, the application problems and future research trend of Cu-based catalysts for catalytic removal of CO were discussed and summarized.

Key words: carbon monoxide, complete oxidation, preferential oxidation, Cu-based catalyst
