Evaluation of a cobalt-molybdenum-boron catalyst for hydrogen generation of alkaline sodium borohydride solution-aluminum powder system

► A newly synthesized Co-Mo-B catalyst is reported. ► The catalyst exhibits remarkably catalytic activity to hydrolysis reaction of NaBH4. ► A hydrogen generation system is composed of NaBH4 solution, catalyst and Al powder. ► This system can yield >6 wt% H2 with fast kinetics and high fuel conversion.
