Abstract
The present study aimed to investigate the effect of different parameters on the hydrogen production rate (HPR) during KBH4 hydrolysis using Co-B (pure) and Co-B@GO (supported) catalysts. The results showed that the HPR value for Co-B@GO catalyst was 2299.81 mL*gcat-1 min-1, which was approximately 2.3 times higher than that of the Co-B catalyst (1012.71 mLgcat-1 *min-1). The activation energy of Co-B@GO was also calculated to be 21.62 kJ/mol, lower than some reported values in the literature. This demonstrates the potential of Co-B@GO as a cost-effective and efficient catalyst for hydrogen production from alkali hydrides. The results of this study provide novel insights into the optimization of hydrogen production processes using supported metal catalysts.
