Abstract

Abstract:

The reduction behavior of CuO supported on ZrO2 and Al2O3 has been investigated by temperature-programmed reduction (TPR) and TG techniques. The oxidation activity of CO on the catalysts has also been studied. It has been found that there is obvious difference between TPR profiles of ZrO2 supported CuO and Al2O3 supported catalysts, the monolayer CuO on ZrO2 is easily reduced, and which leads to a dramatic increase in oxidation activity.

Key words: CuO, ZrO₂, Catalyst, Temperature-programmed reduction(TPR), Interaction
