The invention discloses a preparation method for a NiCoP
nanowire electro-catalytic
electrode. A NiCo salt
nanowire is adopted as a phosphorization precursor,
hypophosphite is used as a
phosphorus source, and the phosphorization process of the NiCo salt
nanowire is achieved by controlling the annealing technique in a
stored program control tube type annealing furnace. The
diameter of the NiCoP nanowire obtained through the method is 140 nanometers, the length of the obtained NiCoP nanowire is about 3.2 micrometers, and the surface of the nanowire is roughly and evenly grown on a 3D netty foamed
nickel substrate, so that the specific surface area and the electric
conductivity of an electro-catalytic material are effectively improved, and the electro-catalytic
hydrogen evolution performance and stability of an
electrode material are improved. The electro-catalytic
hydrogen production performance of the
electrode is tested in 1M of a KOH
electrolyte, the
overpotential under the
electric current density of 10 mA / cm<2> is 109 mV, and the Tafel slope is 88.5 mV / dec, so that the material has the superior electro-catalytic
hydrogen production performance compared with common electro-catalytic
hydrogen evolution materials. Meanwhile, the preparation technique is simple, the
equipment requirement is conventional, reactive materials are abundant, price is low, and the electrode is
environmentally friendly.
