A porous CuO-ZnO composite with sphere type was prepared by sol-gel method.The morphology, phase structure, surface area and reactivity for CO oxidation of the CuO-ZnO composite were characterized by SEM, XRD, BET, TGA and H2-TPR.Effect of pretreatment condition on catalytic performance over porous CuO-ZnO composite has investigated in a fixed bed reactor.CuO-ZnO composite catalyst exhibits higher activity at low temperature than the control catalyst, compositionally identical CuO/ZnO synthesized by CuO impregnation of ZnO (made by sol-gel method). |
