Ultra small nano-sized cobalt catalysts supported on MCM41 have been prepared via simple one-pot synthesis procedure, the microstructure of as-prepared catalysts was characterized by XRD, N₂ adsorption-desorption, SEM, TEM and ICP-AES. The results indicated that the Co/MCM41 catalysts possessed well-ordered mesoporous morphology, and the cobalt loading had negligible influence on MCM41 support. Catalytic hydrogen production experiments demonstrated that the catalyst with the cobalt loading of 0.5 wt% (Co/MCM41–0.5w) exhibited the highest catalytic activity over all investigated catalysts, its turn-over frequency is higher than that of Ru/C catalyst and comparable to that of Co-P/Ni foam catalyst.

通过简单的一锅合成法制备了负载在MCM41上的超小型纳米钴催化剂，通过XRD，N ₂吸附-脱附，SEM，TEM和ICP-AES对所制备的催化剂的微观结构进行了表征。结果表明，Co / MCM41催化剂具有良好的介孔形貌，钴的负载量对MCM41载体的影响可忽略不计。催化制氢实验表明，钴负载量为0.5 wt％（Co / MCM41–0.5w）的催化剂在所有研究的催化剂中均表现出最高的催化活性，其翻转频率高于Ru / C催化剂，并且具有可比性相当于Co-P / Ni泡沫催化剂。
