Catalytic Hydrolysis of Sodium Borohydride
A study has been made of the influence of temperature, NaON, and concentrations of NaBH 4 on the rate of catalytic hydrolysis under isothermal and adiabatic conditions. Finely divided Co/TiO 2 powder was used as the model catalyst. The catalyst preserves its initial activity during 20 cycles, ensuri...

on the rate of catalytic hydrolysis under isothermal and adiabatic conditions. Finely divided Co/TiO
2
powder was used as the model catalyst. The catalyst preserves its initial activity during 20 cycles, ensuring an NaBH
4
conversion of 94–98%. Activation energies equal to 65.6 and 55 kJ/mole have been determined in the aqueous and aqueous-alkaline solution of NaBH
4
respectively. It has been shown that the standard method of determining activation energy without account of sorption/ desorption processes leads to its dependence on the composition of the solution. |
