【Abstract】 a Amorphous Ni-P-based coatings have remarkable corrosion resistance, and have quite active for the hydrogen evolution reaction (HER) to act as promising cathodic materials, which can decrease the overpotential of the HER and reduce energy losses. The influences of P content in Ni-P deposits, fihn thickness, preparation conditions, another adding element, surface oxidation after depositing,pretreatment and heat treatment were analyzed for controlling the electrocatalytic activity of HER. The catalytic mechanism of amorphous Ni-P-hased coatings was discussed.更多还原
