Noble metal-based catalysts with high hydrogen generation rates (HGR) have greater catalytic activity for the hydrolysis of NaBH4 . For the hydrolysis of NaBH 4 , rutheniumbased catalysts were often utilized. Different materials have been used to support noble metalbased catalysts . The HGR of the Ru catalyst was higher than that of the Ni3B and Co3B catalysts, which had HGRs of 1.3 mL/min•g and 6.0 mL/min•g, respectively .
