Catalytic Activity of Water Gas Shift and Characteristic Analysis of Complex Network from Surface Morphology of CuO+ZnO/CeO_2/Al_2O_3

The supported catalyst of water gas shift reaction(WGSR) at low temperature,CuO+ZnO/CeO2 / Al2O3,was prepared using spherical alumina(3mm) and the incipient wetness technique for impregnation.The X-ray diffraction(XRD),Raman scattering spectroscope and scanning electron microscope(SEM) were employed to characterize the chemical composition,bonded state of surface elements and surface morphology of CuO+ZnO/CeO2/Al2O3.The catalytic activity of CuO+ZnO/CeO2/Al2O3 in WGSR at low temperature was measured.On the basis of the network constructed from the surface morphology of CuO+ZnO/CeO2/Al2O3,the topological structure parameters and network synchronism were calculated.Results of the calculations show that the node connectivity of the surface morphology network follow a power-law distribution,and that the network synchronism is increased after CuO+ZnO/CeO2/Al2O3 catalyzes WGSR at low temperature.
