Özet

Catalytic hydrolysis of mixtures of sodium borohydride (NaBH4) and ammonia borane (NH3BH3) was studied for hydrogen production. For hydrolysis, novel tri-metallic (Ni-B-Zr) and bimetallic (Ni-B) catalysts was prepared and used. Experiments conducted at different reactant molar ratios and temperatures. Comparing Ni-B and Ni-B-Zr for pure NaBH4 and pure NH3BH3 reactions, positive effect on hydrogen production provided by Zr on Ni-B catalyst was obtained. SEM, BET Kinetic analysis for hydrolysis reactions were carried out and activation energies of hydrolysis reactions of pure NaBH4, pure NH3BH3, and NaBH4/NH3BH3 molar ratios were calculated
