P-doped noble-metal-free CoB nanoparticles (NPs) anchored on a three-dimensional nitrogen-doped graphene hydrogel (NGH) have been successfully synthesized trough a simple one-pot co-reduction method and further used as catalyst toward catalytic hydrolysis of ammonia borane (NH3BH3) at room temperature. Benefiting from the synergistic electronic effect between Co, B, and P, as well as the strong metal-support interaction between CoBP and 3D NGH, the as-synthesized Co0.79B0.15P0.06/NGH catalyst exhibits excellent catalytic activity toward hydrolysis of ammonia borane, with the turnover (TOF) value of 32.8 min(-1), which is almost 5 times higher than that of undoped Co0.85B0.15/NGH NPs, and higher than most of the reported noble metal free catalysts.
