Kinetics of the Catalytic Hydrolysis of Concentrated Aqueous Solutions of Nabh4 on Co/Tio2 Powder

Abstract

The results of experimental studies on the hydrolysis of concentrated aqueous solutions of sodium borohydride in a concentration range of 1.05-6.3 mol/kg at temperatures of 20-80 degrees C with the use of Co/TiO2 powder as a model catalyst are presented. Based on the results of the experiments, an approximation of the rate of the process was proposed for the kinetic regime of hydrolysis taking into account the non-single-channel nature of hydrolysis due to the introduction of a linear dependence of the activation energy on the degree of hydrolysis.
