Hydrogen production by sodium borohydride in NaOH aqueous solution

The kinetics of hydrolysis reaction of NaBH₄ in NaOH aqueous solution is studied. The influence of pH of the NaOH aqueous solution on the rate of hydrogen production and the hydrogen production efficiency are studied for the hydrolysis reaction of NaBH₄. The results show that the activation energy of hydrolysis reaction of NaBH₄ increased with the increase of the initial pH of NaOH aqueous solution.With the increasing of the initial pH of NaOH aqueous solution, the rate of hydrogen production and hydrogen production efficiency of NaBH₄ hydrolysis decrease.
