Hydrogen generation from hydrolysis of NH3BH3 by an electroplated Co–P catalyst

This paper investigates the effect of an electroplated Co–P catalyst on hydrogen generation kinetics from hydrolysis of NH3BH3. The Co–P catalyst is composed of an amorphous Co–P phase and Co nanoparticles. An increase in NH3BH3 concentration caused the hydrogen generation rate to increase dramatically. The Co–P catalyst shows a large hydrogen generation rate for 2 wt% NH3BH3 solution at 30 °C. This is 1.8 times higher than that of the Pt/C catalysts and 6 times higher than that of Ru catalysts. The activation energy for hydrolysis of NH3BH3 by the Co–P catalyst is calculated to be 22 kJ/mol, which is close to that of noble metal-based catalysts.
