| 概要 |
The environmentally friendly combustion of hydrogen makes hydrogen an ideal fuel. Research on the ideal hydrogen storage is still being carried out. one candidate for hydrogen storage is NaBH_4. NaBH_...4 is hydrolyzed to release hydrogen. This work concerns the hydrolysis reaction of NaBH_4 to release hydrogen with a catalyst Ni-Cu-B deposited on hydroxyapatite. The research went through 2 stages, namely catalyst synthesis and NaBH_4 hydrolysis reaction. The catalyst synthesis was carried out electrochemically using a 2-compartment electrochemical cell at the certain current density and reaction time. The hydrolysis reaction was observed in a batch reactor at a constant temperature. The results showed that the most significant hydrogen release at room temperature occurred with a catalyst made at 160 mA/cm2 for 90 minutes. The hydrogen release rate ranged from 435 to 1600 mL H_2/g catalyst/min. The resulting equation for the reaction rate constant as a function of temperature is k = 3.567 x 1010 exp(8624.245/T).続きを見る
