| Abstract: In this paper, a simple calcination process was used to synthesize nanocrystalline cobalt boride (CoB), which was employed to catalyze the hydrolysis of ammonia borane solution at room temperature. Specifically, it was found that the CoB exhibited high performance with a turnover frequency (TOF) of 35.3 molH2·molcat-1·min-1, which is superior to platinum (TOF=29.3 molH2·molcat-1·min-1). It still possessed excellent catalytic hydrogen production performance after repeated testing for 8 times. We found that Co0 species on the surface of CoB is a possible catalytic active site, and the boron site on the surface can effectively assist the Co0 site to achieve the synergistic catalytic hydrogen production from ammonia borane. |
