The development of non-noble metal hydrogen evolution electrocatalysts is of practical significance for solving the current serious energy crisis. NiCoP nanorod arrays were grown on nickel foams on conductive metal substrates in situ. The self-supporting alloy electrode material exhibites excellent electrocatalytic hydrogen evolution performance. When the current density reach 10 mA/cm2 in 1 mol/L potassium hydroxide electrolyte, only 93 mV overpotential is required.In addition, the catalyst has lower Tafel slope, higher charge transfer resistance and higher catalytic stability.
