| Abstract: | 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/cm^2 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. |
