摘      要：The Ni-Fe-TiO_(2) overlayers on mild steel strips were prepared by electrochemical *** layers were characterized morphologically by confocal laser scanning microscopy and scanning electron microscopy(SEM) coupled with energy-dispersive spectroscopy(EDS)*** layers exhibit a quasi-three-dimensional(3D)morphology in which the crystalline,TiO_(2),is *** activity of the Ni-Fe-TiO_(2) layers for the hydrogen evolution reaction(HER) was assessed by using pseudo-steady-state polarization curves and electrochemical impedance spectroscopy(EIS) in alkaline *** results were compared with the properties of Ni-Fe electrodes and used for determining the mechanism and kinetics of *** comparison with Ni-Fe electrodes,the synthesized Ni-Fe-TiO_(2) electrodes present higher catalytic activity for HER due to the increase in the real surface area and high intrinsic elec trocatalytic activity of titanium *** present study provides valuable insight for exploring practical applications of Ni-based alloys as hydrogen evolution electrodes.
