【Abstract】 he catalytic active center of catalyst XYF-5 for hydrogenation of maleic anhydride has been studied by XRD and AES. Cu0 in Cu-ZnO solid solution is found to exist after reducing the catalyst, and ZnO can be partially reduced with the formation of oxygen--deficient structureZnOx (x≤1 ). The active center is suggested to be Cu--Zn -- O("□" is oxygen vacancy) existing in Cu-ZnO solid solution.更多还原
