What is Hydrogen generation from catalytic hydrolysis of sodium borohydride solution using Cobalt–Copper–Boride (Co–Cu–B) catalysts about?

CoeCueB, as a catalyst toward hydrolysis of sodium borohydride solution, has been prepared through chemical reduction of metal salts, CoCl 2 $6H 2 O and CuCl 2 , by an alkaline solution composed of 7.5wt% NaBH 4 and 7.5wt% NaOH. The effects of Co/Cu molar ratio, calcination temperature, NaOH and NaBH 4 concentration and reaction temperature on catalytic activity of CoeCueB for hydrogen generation from alkaline NaBH 4 solution have been studied. X-ray diffraction (XRD), scanning electron microscope (SEM) and Nitrogen adsorptionedesorption isotherm have been employed to understand the results. The CoeCueB catalyst with a Co/Cu molar ratio of 3:1 and calcinated at 400 C showed the best catalytic activity at ambient temperature. The activation energy of this catalytic reaction is calculated to be 49.6 kJ mol À1 .
