| 英文摘要 | the mn doping nanocrystalline co-ce-zr-o-x catalysts were prepared by the co-precipitation method and characterized by various physico-chemical characterization techniques such as x-ray diffraction (xrd), temperature- programmed reduction (tpr), o-2 temperature-programmed desorption (o-2-tpd). x-ray photoelectron spectroscopy (xps) and temperature-programmed hydrogenation (tph). their catalytic performances for methane reforming with co2 to hydrogen and carbon monoxide were investigated. adding mn remarkably enhanced the catalytic activity and stability of the co-ce-zr-o-x catalyst. the highest catalytic activity and long-term stability was obtained when the molar ratio of mn/(ce + zr + mn) was 10%. the improved catalytic behavior was closely related to the surface oxygen species and oxygen mobility. in comparison with that of co-ce-zr-o-x catalyst, the migration of bulk lattice oxygen species became easier, and the content of surface oxygen species was higher for the mn-doped nanocrystalline co-ce-zr-o-x samples. tph characterization showed that the surface coke species could be easily oxidized into cox for the mn-doped nano cobalt-composite catalyst due to the higher amount of mobile oxygen. the mn incorporation promoted the dispersion of the nano-sized coox crystallites. in comparison with the impregnated samples, coox species dispersed better in the co-precipitated catalysts.
