Design and Development of Highly Efficient Ni/ZnO Catalysts Based on Semiconductor Metal Oxide Catalysis Theory

In the context of reactive adsorption desulfurization,the development of an efficient Ni/ZnO desulfurizer has attracted increasing attention.In the work reported here,a novel Ni/Mn-ZnO composite nanowire desulfurizer is designed on the basis of the catalytic theory of semiconductor metal oxides and the characteristics of one-dimensional nanomaterials.X-ray diffraction,scanning electron microscopy,N_(2) adsorption-desorption,and X-ray photoemission spectroscopy demonstrate that Mn doping changes the crystal structure and morphology of the Ni/ZnO desulfurizer,increases the number of quasi-free electrons in the ZnO,and promotes H_(2)S adsorption.The Ni/Mn-ZnO composite nanowire desulfurizer exhibits good desulfurization performance when used with gasoline as the raw material.
