| Abstract: | Hydrogen generation from catalytic hydrolysis of aqueous NaOH-stabilized sodium borohydride solutions was investigated using platinum catalysts dispersed on active carbon, carbon black, and alumina supports. The Pt/C catalyst shows high catalytic activity due to the large BET surface area of active carbon support. The investigations on the effects of Pt loading and calcination temperature on the performance of Pt/C catalyst were also performed. After filtration from the reaction medium and rinsing with water, the used catalyst was re-evaluated and almost the same catalytic activities as fresh catalyst were obtained during several cycles. |
