| 2 | Effects of the partial replacement of La by M(M=Ce,Ca and Sr) in La_(2-x)M_xCuO_4 perovskites on catalysis of the water-gas shift reaction显示文摘The performance of La2-x M x CuO4 perovskites (where M=Ce,Ca or Sr) as catalysts for the water-gas shift reaction was investigated at 290℃ and 360℃.The catalysts were characterized by EDS,XRD,N2 adsorption-desorption,XPS and XANES.The XRD results showed that all the perovskites exhibited a single phase (the presence of perovskite structure),suggesting the incorporation of metals in the perovskite structure.The XPS and XANES results showed the presence of Cu2+ on the surface.The perovskites that exhibited the best catalytic performance were La 2 x Ce x CuO 4 perovskites,with CO conversions of 85% 90%.Moreover,these perovskites have higher surface areas and larger amounts of Cu on the surface.And Ce has a higher filled energy level than the other metals,increasing the energy of the valence band of Ce and providing more electrons for the reaction.Besides,the La1.80Ca0.20CuO4 perovskite showed a good catalytic performance. | S.S.Maluf E.M.Assaf | 2010 | Journal of Natural Gas Chemistry2010，19，6： | 1 |
