Abstract:

An inverse CeO₂/CuO catalyst is a novel catalyst for low-temperature oxidation of CO in H₂ rich gas，with higher activity than traditional CuO/CeO₂ catalysts. This paper summarizes the preparation methods of CeO₂/CuO catalysts，including inverse microemulsion and impregnation methods，and speculates the influence of size effect and interfacial effect on the performance of CeO₂/CuO catalysts. Moreover，it presents the development of CeO₂/CuO catalysts in the future，in order to look for the appropriate size of CuO and CeO₂ particles and improve selectivity and stability of CeO₂/CuO catalysts for CO preferential oxidation.
