Hydrogen Generation by Using Hydrolysis of Sodium Borohydride

Related Articles

Abstract A safe,simple,compact process generating high-purity of hydrogen gas on demand from base-stabilized,aqueous solutions of sodium borohydride(NaBH_4) is proposed.When NaBH_4 solution reacts with the catalysts,it spontaneously hydrolyzes to form hydrogen gas and sodium borate,a water-soluble inert salt.Using aqueous solutions of sodium borohydride can reduce the dangers of H_2 stored for a long time.In this reaction,the hydrogen generation rate can be easily controlled,and the hydrogen gas is very pure and needn't refine.The catalysts can be circularly used.Furthermore,hydrogen gas can be produced under(0 ��) and no pollution to environment.Also the catalysts and generators designed in author's laboratory are introduced,experiments show the catalysts are cheap,and the generators are safe and easily controlled.
