Abstract

Abstract: The catalytic activity of COoxidation on Pd/Al₂O₃catalysts doped with ZrO₂was examined in different atomspheres.The interaction of Zr-Al,the effect of property of the desorption-renewal of oxygen specie,on the catalysts was investigated by XRD,TPR and TPD-MS techniques.The results showed that suitable amount of ZrO₂would promote the desorption and renewal of oxygen species on catalysts.Thus,it increased the activities of COoxidation and the reaction between H₂and O₂on the catalysts.The catalyst doped with ZrO₂showed the best reactivity.

Key words: Catalytic oxidation, ZrO₂, Pd
