A series of catalysts were prepared using molybdenum sulfide clusters as precursors and their catalytic performance for higher alcohols synthesis was evaluated. It was found that the cluster precursors could provide well-dispersed MoS₂ particles and a number of coordinated unsaturated Mo sites with all the catalysts in varying degrees, which were favorable for the formation of intermediate active phases thereby enhancing catalytic performance. In particular, K-NiMo₃S_x catalyst obtained by using heterobimetallic cluster NiMo₃S₁₃ as precursor exhibited the highest activity with the space-time-yield (STY) of total alcohols (497 mg/g/h) and the selectivity of higher alcohols (59.71%), which could be attributed to the interaction effect of the Ni promoter and Mo species and the resultant formation of active phase NiMo₃S_x. Thus, the most key factor for obtaining highly efficient molybdenum sulfide catalysts was to produce a number of coordinated unsaturated sites, on which abundant NiMoS active phase can be formed and the formation of bulk inactive phase should be avoided.

以硫化钼簇为前驱体制备了一系列催化剂，并评估了它们对高级醇合成的催化性能。发现簇状前体可以在所有催化剂不同程度上提供分散良好的MoS ₂颗粒和许多配位的不饱和Mo位点，这有利于中间活性相的形成，从而增强了催化性能。特别地，通过使用异双金属簇NiMo ₃ S ₁₃获得的K-NiMo ₃ S _x催化剂前驱体以总醇的时空产率（STY）表现出最高的活性（497 mg / g / h）和高级醇的选择性（59.71％），这可能归因于Ni促进剂的相互作用和Mo物种和形成的活性相NiMo ₃ S _x的形成。因此，获得高效的硫化钼催化剂的最关键因素是产生许多配位的不饱和位点，在这些位点上可以形成大量的NiMoS活性相，应避免形成块状的惰性相。
