Preparation of Catalyst for Hydrogen Production Reaction of Sodium Borohydride and Its Effectiveness

The fundamental purpose of this study is to produce a catalyst for catalyzing the hydrogen production reaction of sodium borohydride (NaBH4). The catalyst for catalyzing this reaction includes a catalyst carrier and a metal catalyst. We use three catalyst bed temperatures with the same γ-Al2O3 carrier and gas sensor, with different chelate concentration processes to make the catalyst. The metal catalyst selected is Co. The effects of the catalyst produced by different catalyst carrier processes on the hydrogen production efficiency and total hydrogen yield of NaBH4 solution are discussed. The experiment shows that when the catalyst soaked in 30 wt% Co/γ-Al2O3 is used at 70 ℃, the rate and hydrogen production efficiency are 5300 ml/min g cat and 82.92%, respectively. The catalyst has a vigorous hydrolytic hydrogen production reaction with NaBH4. This catalyst can be combined with a fuel cell system for hydrolytic hydrogen production to generate power in the future, enabling the portability and efficiency of stored hydrogen to be enhanced effectively.
