Hydrogen generation from sudiumborohydrideusing Co-Bpowder catalyst |
| 초록 |
Generation of hydrogen via the hydrolysis of sodium borohydride (NaBH4) solution in the presence of metal catalysts is a promising method for hydrogen storage. For hydrogen generation form a NaBH4 solution. Co-B catalyst was prepared by the chemical reduction method using NaBH4 and CoCl2 as a reduction chemical. The characters of Co-B catalyst were studied by using scanning electron microscopy(SEM), nitrogen adsorption-desorption, FT-IR, and energy dispersive sepectroscopy(EDS).Effect of solvent compound ratio, feeding rate of solvent and amount of catalyst loading on hydrogen generation rate were investigated. Solvent dissolving NaBH4 was Methanol (MeOH), 5wt% NaOH solution, and mixture. We were used to pump for feeding solvent in reactor. The pump rate was between 1 ml/min and 100ml/min. |
