Abstract
In this study, Langmuir–Hinshelwood and Michaelis–Menten kinetic models are applied to describe the kinetic behaviour of the Co–B catalyst in the hydrolysis of 0.12 M aqueous solutions of boron hydrides at temperatures from 22 to 60°C. Boron hydrides are selected as sodium borohydride (NaBH4, 10 wt % NaOH) and ammonia borane (NH3BH3). Based on the Langmuir–Hinshelwood kinetic approach, it is found that under the same reaction conditions the NaBH4–Co–B catalyst interaction is more effective than that of the NH3BH3–Co–B. According to the Langmuir–Hinshelwood model, apparent activation energies (Ea) for the hydrolysis of NaBH4 and NH3BH3 over Co–B catalysts are calculated to be 45.38 and 57.37 kJ/mol, respectively.
