Hydrolytic dehydrogenation of amine-boranes catalyzed by graphene supported rhodium–nickel nanoparticles

•One-step synthesis of graphene supported RhNi NPs•The catalysts exhibit excellent catalytic activity.•The catalysts show good durable stability.

Well dispersed rhodium–nickel (RhNi) nanoparticles (NPs) supported on graphene have been synthesized through an in situ co-reduction procedure under ambient condition, which shows high catalytic activity and durability for hydrolysis of ammonia borane and methylamine borane.
