A layered composite of graphene supported with ultrafine Ni<sub>3</sub>B nanoparticles (Ni<sub>3</sub>B/G) is designed and synthesized, which acts as catalyst and confinement carrier for Li/KBH<sub>4</sub>.

The graphene effectively disperses Ni<sub>3</sub>B nanoparticles and confines the Li/KBH<sub>4</sub> in its interlayers. The confinement of Li/KBH<sub>4</sub> and the catalysis of Ni<sub>3</sub>B nanoparticles, assisted with the high thermal conductivity of graphene, contribute synergistically the hydrogen storage of Li/KBH<sub>4</sub>.

Our results revealed a size-dependent behavior in reaction efficiency, with the catalyst achieving the highest catalytic activity (93 % selectivity in primary amine) at a particle size of 5.62(3) nm.
