文摘Cu-ZnO/Oxide catalysts wre prepared by deposition which were used for Maleic Anhydride hydrogenating to γ-BL All these catalysts have so good activity and selectivity that these catalysts surpassed one kind of industrial catalyst which was often used in industry The catalyst supported by Al2O3-TiO2 has best activity and selectivity; The catalyst supported by CeO2 has good low-temperature activity which possesses a giant potency for saving energy The results of TPR, XRD and XPS showed that Oxides was the main phases before reducing and only the CuO was reduced to Cu0 Cu0 was the active and the catalyst with good dispersion had good catalytic, such as the catalyst of 50CuO-40ZnO/10(Al2O3-10TiO2)
