알칼리 NaBH4 용액에서 Co-B 촉매를 이용한 수소발생반응에 관한 연

Abstract

For hydrogen generation from aqueous alkilne NaBH4 solution, Co-B catalyst was prepared by chemical reduction method using NaBH4 as a reduction chemical. Effects of solution temperature, amount of catalyst loading, NaBH4 concentration, and NaOH (a base-stabilizer) concentration on the hydrogen generation rate were exmanined. Compared to Ru catalyst generally used, the low-cost Co-B catalyst exhibited almost comparable activity to the hydrogen generation reaction.
