Abstract

This is the first study to produce hydrogen from the potassium borohydride (KBH₄) hydrolysis using boric acid (H₃BO₃). The effect of H₃BO₃ addition on the hydrogen production via KBH₄ hydrolysis was investigated for different H₃BO₃ and KBH₄ molar ratios. In addition, the temperature effect on the hydrolysis reaction was investigated at different temperatures. H₃BO₃ showed good catalytic activity to produce hydrogen from KBH₄ hydrolysis. Activation energy to produce hydrogen from KBH₄ hydrolysis was found to be 20.31 kJ/mol. This work also includes kinetic information for the hydrolysis of KBH₄. According to the kinetic studies, the reaction between H₃BO₃ and KBH₄ had a reaction order of 0.24 against the H₃BO₃ concentration, while it had a reaction order of 0.16 against the KBH₄ concentration.
