ResumoAbstract A novel synthesis strategy is demonstrated to prepare Mo 3 P/Mo nanobelts with porous structure for the first time. The growth and formation mechanism of the porous Mo 3 P/Mo nanobelt structure was disclosed by varying the contents of H 2 /PH 3 and the reaction temperature. During the hydrogen evolution reaction (HER) catalysis, the optimized porous Mo 3 P/Mo nanobelts exhibited a small overpotential of 78 mV at a current density of 10 mA cm −2 and a low Tafel slope of 43 mV dec −1 , as well as long‐term stability in alkaline media, surpassing Pt wire. Density functional theory (DFT) calculations reveal that the H 2 O dissociation on the surface of Mo 3 P is favorable during the HER.
