• Nano-sized cobalt catalyst
• MCM41
• Alkaline borohydride hydrolysis
• Hydrogen production

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, N-2 adsorption-desorption SEM, TEM and ICP-AES. The results indicated that the Co/MCM41 catalysts possessed well-ordered mesoporou: 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/( catalyst and comparable to that of Co-P/Ni foam catalyst.
