Abstract Sodium borohydride tablets have been employed as hydrogen-storage materials. Hydrogen release was performed by acidic hydrolysis where solutions of sulfuric and hydrochloric acids were added to the tablets, and by catalytic hydrolysis where water was added tablets of solid-state NaBH4/Co composite. In acidic solutions hydrogen evolution occurred instantaneously, and at high concentrations of acids the releasing hydrogen contained an admixture of diborane. Hydrogen evolution from the solidstate NaBH4/Co composite proceeded at a uniform rate of 13.8±0.1 cm3·min-1, water vapor being the only impurity in the evolving gas.

Sodium borohydride hydrolysis is one of the promising methods for the supply of hydrogen on-board in fuel cell vehicle. A suitable catalyst is required to control the hydrogen release from stable alkaline sodium borohydride solution. The present paper reports the effect of Co (II) doped zeolite-X and K-chabazite catalysts in sodium borohydride hydrolysis reaction. Kinetics of the hydrolysis reaction was observed to get enhanced by the use of these catalysts. Activation energies for Co (II) doped K-chabazite and zeolite-X are found to be 30.7 and 48 kJ mol-1, respectively.
