Kinetic study of NaBH4 hydrolysis over carbon supported ruthenium

The effects of temperature and the concentrations of NaBH4, NaBO2 and NaOH on the rate of NaBH4 hydrolysis over carbon supported ruthenium catalyst were investigated using isothermal rate data extracted from non-isothermal reactions. It was shown that the hydrolysis was a zero-order reaction with respect to the concentration of NaBH4 and the reaction rate decreased with the increase of OH- concentration. A rate expression was then derived to correlate the hydrolysis rate with the temperature and NaOH concentration.
