Synthesis of Fe0.3Co0.7/rGO nanoparticles as a high performance catalyst for the hydrolytic dehydrogenation of ammonia borane

Well-dispersed Fe0.3Co0.7/rGO nanocatalysts have been synthesized utilizing the two-step reduction method and successfully employed in the hydrolysis of ammonia borane (NH3BH3 AB) at room temperature. The mass percent of the supported Fe0.3Co0.7 nanoparticles (NPs) on graphene (rGO) sheets can reach to the maximum value of 50 wt%. The as-synthesized catalysts exerted satisfying activity and reusability for the hydrolytic dehydrogenation of AB at 298 K, especially for the specimen of 50 wt% Fe0.3Co0.7/rGO NPs. The catalytic hydrolysis reaction was rapidly completed within 1 min.
