Abstract
For hydrogen generation from aqueous alkilne $NaBH_4$ solution, Co-B catalyst was prepared by chemical reduction method using $NaBH_4$ as a reduction chemical. Effects of solution temperature, amount of catalyst loading, $NaBH_4$ 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.
