The technology of catalytic hydrolysis of sodium borohydride solution, a safe and practical way of producing hydrogen, has become one of the hotspots in the research of hydrogen generation. The preparation of efficient catalysts is the key problem of the technology. Metal catalysts have been extensively investigated in the hydrolysis of sodi- um borohydride due to their high catalytic activity and low activation energy. The paper introduces basic principles of catalytic hydrolysis of NaBH4 solution, reviews the devel- opment status of metal catalysts and puts forward the problems and countermeasures in the process of sodium borohydride hydrolysis. At last, the development direction of the metal catalysts is pointed out.
