Abstract
Porous Co-P catalysts electroplated on Cu in chloride based solution with an addition of $NaH_2PO_2$ and glycine were developed for hydrogen generation from alkaline $NaBH_4$ solution. The microstructures of the Co-P catalysts and their hydrogen generation properties were analyzed as a function of cathodic current density and plating time during the electrodeposition. Amorphous Co-P electrodeposits with porous structure was formed on Cu at cathodic current density of $0.05\;A/cm^2$, and showed very high hydrogen generation rate in alkaline $NaBH_4$ solution due to an increase in the surface area of the catalyst as well as the catalytic activity. The Co-P catalyst, which was obtained at cathodic current density of $0.05\;A/cm^2$ for 5 min, exhibited the best hydrogen generation rate of 2290 ml/min.g-catalyst in 1 wt. % NaOH+10 wt. % $NaBH_4$ solution at $30^{\circ}C$.
