| Abstract: Herein, nickel phosphides nanoparticles with different phases were successfully prepared by multi-step calcination and phosphidation process at low temperature using Ni based MOF (Ni-MOF) as the precursor. The resulting materials were applied to the hydrogen evolution reaction (HER) catalyst, Ni1P1-500 obtained at a mass ratio of Ni@C to red phosphorus of 1:1 and a pyrolysis temperature of 500℃ exhibited a remarkably enhanced electrocatalytic performance with a current density of 10 mA·cm-2 at an overpotential of 178 mV and a superior durability for the HER in acid media. A small Tafel slope of 62 mV·dec-1 revealed a Desorption-Heyrovsky mechanism during the HER. The excellent electrocatalytic performance might be ascribed to the presence of the proton acceptor (P site) and hydride-acceptor (Ni site) centers on the surface of nickel phosphide. |
