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
