Zeolite Supported Cobalt Catalysts for Sodium Borohydride Hydrolysis
View through CrossRef
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.
