Hydrogen generation from hydrolysis of ammonia-borane using Pd-PVB-TiO2 and Co-Ni-P/Pd-TiO2 under stirred conditions

► By-product coverage causes a significant external mass transfer resistance. ► Pd-PVB-TiO2 and Co-Ni-P/Pd-TiO2 are active catalysts in the hydrolysis of H3NBH3. ► Pd-PVB-TiO2 provides max HG rate of 14,800 mL H2 min−1 (g Pd)−1 at 55 ± 0.5 °C. ► Co-Ni-P/Pd-TiO2 provides max HG rate of 1390 mL H2 min−1 (g cat)−1 at 55 ± 0.5 °C. ► HG rate is independent of H3NBH3 under stirred condition.
