| 英文摘要 | the effects of loading and molar ratio on the structure and reducibility of nio-moo3/gamma-al2o3 catalysts have been investigated. particular attention is given to the catalysts with excess of mo. the catalysts were prepared by impregnation method and characterized by raman spectroscopy, x-ray photoelectron spectroscopy (xps), x-ray diffraction (xrd), and temperature-programmed reduction techniques. results from raman, xps, and xrd show that different surface species can be formed depending on the loading and molar ratio. at low loading spinel-like nial2o4 and dispersed moo3 are the major species on gamma-al2o3, with increasing the loading the aggregation of the mo species occurs. only at high loading are crystalline beta-nimoo4 and moo3 formed on the surface. for the first time, excess mo was found to promote the formation of beta-nimoo4 on gamma-al2o3. the change in the structure of the catalysts has a large influence on their reducibility, suggesting that both the structure and oxidation-reduction properties of the nio-moo3/gamma-al2o3 catalysts can be controlled by varying the loading and molar ratio. |
