Nowadays, it is particularly important to develop efficient hydrogen evolution catalyst in the process of water electrolysis. In this paper, a monometallic phosphide ( Ni2P@C ) was synthesized through a simple one-step calcination and phosphorization process, which was a high efficient catalyst for hydrogen evolution reaction. Ni2P@C exhibits satisfactory activity with a low overpotential of 215 mV and small Tafel slope of 105 mV dec −1 at the current density of 10 mA cm −2 . In addition, the catalyst displayed favorable stability for 16 h when current density maintained at 10 mA cm −2 . This work provides reference for monometallic phosphates as catalyst for hydrogen evolution.
