Sodium Borohydride의 수소 발생을 위한 다공성 Co-P 촉매 = Development of Porous Co-P Catalyst for Hydrogen Generation by Hydrolysis of NaBH4

다국어 초록 (Multilingual Abstract)

Porous Co-P catalysts electroplated on Cu in chloride based solution with an addition of NaH2PO2 and glycine were developed for hydrogen generation from alkaline NaBH4 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/cm2, and showed very high hydrogen generation rate in alkaline NaBH4 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/cm2 for 5 min, exhibited the best hydrogen generation rate of 2290 ml/min.g-catalyst in 1 wt.% NaOH+10 wt.% NaBH4 solution at 30oC .
