| 英文摘要 | Nickel and potassium promoted beta-mo2c catalysts were prepared for co hydrogenation to higher alcohols synthesis. the results revealed that beta-mo2c produced mainly hydrocarbons, but the addition of potassium resulted in a remarkable selectivity shift from hydrocarbons to alcohols over beta-mo2c. moreover, it was found that potassium enhanced the ability of chain propagation of beta-mo2c catalyst and led to a higher selectivity to c2+oh. the addition of nickel further enhanced higher alcohols synthesis, which showed the optimum at 1/8-1/6 of ni/mo molar ratios. the characterization suggested that there might be a synergistic effect of potassium and nickel on beta-mo2c, which favored the alcohols synthesis. the production of alcohols appeared to be relevant to the presence of mo4+ species, whereas the formation of hydrocarbons was closely associated with mo2+ and/or mo-o species on the surface of beta-mo2c-based catalysts.
