摘要

Sodium borohydride (NaBH4) is considered as being a promising hydrogen carrier. The monolith supported-catalyst is highly prized in the practical NaBH4-based hydrogen generation system due to simple design of hydrogen generator, controllability of reaction and easy separation from the spent solution. In the present study, honeycomb ceramic monolith supported cobalt-molybdenum-boron catalyst was prepared using a modified electroless plating method. The resultant catalyst exhibits an impressive activity towards hydrolysis of NaBH4 solution, which can release 4.2 wt% H-2 in 20 wt% stabilized NaBH4 solution with fast kinetics and 100% fuel conversion, but its catalytic activity gradually declines over cycles. To recover the initial reactivity of catalyst, low temperature calcination treatment at 120 degrees C in air was found to be an effective reactivation method towards the deactivation of catalyst in hydrolysis of NaBH4.
