| 英文摘要 | Potassium and nickel doped beta-mo2c catalysts were prepared and their performances of co hydrogenation were investigated. the main products over beta-mo2c catalyst were hydrocarbons, and only few alcohols were obtained. the potassium promoter resulted in remarkable selectivity shift from hydrocarbons to alcohols over beta-mo2c. moreover, it was found that the potassium promoter enhanced the ability of chain propagation of beta-mo2c catalyst and resulted in a higher selectivity to c2+oh. when doped by potassium and nickel, beta-mo2c catalyst showed high activity and selectivity for mixed alcohols synthesis, the ni promoter further enhanced the whole chain propagation to produce alcohols especially for the step of c1oh-c2oh. from the xps analysis, it had been proved that the formation of higher alcohols might be attributable to the presence of mo-iv species, whereas the formation of hydrocarbons was closely associated with the presence of mo-ii species on the surface of the catalysts.
