Cobalt boride catalysts for hydrogen generation from alkaline NaBH4 solution
چکیده انگلیسی
Cobalt boride precursors were synthesized via chemical reaction of aqueous sodium borohydride with cobalt chloride, and followed by heat-treating at various temperatures. The as-prepared Co-B catalysts were characterized and analyzed by X-ray diffraction (XRD), nitrogen adsorption-desorption and catalytic activity test; and were adopted to help accelerating hydrolysis reaction of NaBH4 alkaline solution. The Co-B catalyst treated at 500 °C exhibits the best catalytic activity, and achieves an average H2 generation rate of 2970 ml/min/g, which may give a successive H2 supply for a 481 W proton exchange membrane fuel cell (PEMFC) at 100% H2 utilization.
