| 英文摘要 | the gamma-alumina supported chromium oxide catalysts with cr loadings varying from 1.7 to 13.6 wt.% were prepared by the impregnation method and characterized using n-2 adsorption, x-ray diffraction (xrd), x-ray photoelectron spectroscopy (xps), uv-vis spectroscopy and raman spectroscopy. benzene combustion catalyzed by the catalysts was investigated. the results showed that chromia was well dispersed on the surface of gamma-al2o3 with a monolayer dispersion capacity of 7.5 wt.%. for the supported chromia catalyst with a cr loading of 1.7 wt.%, only cr6+ species were observed. increasing cr loading to 5.1 wt.% led to the presence of both cr3+ and cr6+ species. catalytic benzene combustion over the catalysts was found to be strongly dependent on cr loading amount. for supported chromia catalyst with a cr loading of 8.5 wt.%, complete benzene combustion was achieved at 350 degrees c which was substantially lower than the temperature for other catalysts, indicating that supported chromia catalyst at a near monolayer dispersion capacity exhibited the optimum catalytic behavior for benzene combustion.
