摘要：

The ordered mesoporous Cu-CeO2 and Cu-Co-CeO2 were prepared by nanocasting method using KIT-6 as hard template. Their application in water gas shift (WGS) were investigated. It is demonstrated that the addition of Co promotes CO conversion and thermal stability. The superior WGS catalytic properties in Cu-Co-CeO2 are associated with the formation of Co2O3 and Co3O4 species providing CO adsorption sites and the existence of more Lewis and Bronsted acid sites.
