Abstract

Abstract: The effect of ZrO₂ modification of γ-Al₂O₃ and CuOcontents on the property of COoxidation and the reduction behavior of CuO/γ-Al₂O₃ catalysts were investigated by TPR, TGand flowing reaction methods.The results indicate that ZrO₂ modification of γ-Al₂O₃ support could increase the activity of COoxidation of CuO-supported catalysts at low copper loading(CuO<15 %) - The presence of ZrO₂ increased the BETsurface area of the catalysts and the amount of reducible CuO.

Key words: CuO/γ-Al₂O₃, catalyst, ZrO₂, TPR
