Preparation and Characterization of Ce0.67Zr0.33O2 and the Activity of Its Sup-ported Only-Pd Three-Way Catalysts

Abstract

Abstract: This investigation focused on the effect of preparation methods for only-Pd/ Ce0.67Zr0.33O2 catalysts on the three-way reaction performance. The results showed that preparation methods have great effect on the support properties. The PdO species on Ce0.67Zr0.33O2 prepared by the co-precipitation method exhibited high reducibility before and after aging. The only-Pd catalysts have excellent three-way catalytic activity.

Key words: ceric oxide, zirconia, preparation method, palladium, three-way catalyst
