Abstract
The effect of ZrO2 modification of gamma-Al2O3 and CuO contents on the property of CO oxidation and the reduction behavior of CuO/gamma-Al2O 3 catalysts were investigated by TPR, TG and flowing reaction methods, The results indicate that ZrO2 modification of gamma-Al2O3 support co uld increase the activity of CO oxidation of CuO-supported catalysts a t low copper loading (CuO <15%). The presence of ZrO2 increased the BE T surface area of the catalysts and the amount of reducible CuO.
