摘要
用XRD、TPR和TPD-MS等手段表征了浸渍法制备的CuO/ZrO2催化剂,发现ZrO2上高度分散的氧化钢具有显著的易被还原和再氧化的特性,从而导致催化剂具有高的CO氧化活性.
Copper/Zirconia catalysts were prepared by impregnation method andcharacterized by XRD, TPR and TPD-MS. It was concluded that four oxygen desorption peaks fromtwo different temperature ranges were related to oxygen species of surface adsorption,highly-dispersed copper oxide on ZrO2 and CuO phase, respectively, and the highly-dispersedcopper oxide was easily reduced, which leads to a dramatic increase in oxidation activity.
