钼

The catalyst samples were characterized by XPS and the catalytic performance of the catalyst for synthesis of lower alcohols was investigated. The XPS results indicated that the molybdenum exists as Mo6+ and (Mo6++Mo4+) in the unreduced and reduced catalyst, respectively, while the cobalt exists as Co2+ in both unreduced and reduced catalyst.

结果表明，在氧化态超细Mo-Co-K催化剂中，钼和钴分别以Mo6+和Co2+物种存在，催化剂中各物种之间存在着相互作用；随着Co/Mo比的增大，还原态催化剂中Mo4+物种的含量逐渐增大并出现极大值；催化剂上合成低碳醇反应性能与其表面的Mo4+物种有关。
