In search for an efficient and low cost electrode material, porous Ni-Cr-Mo-Cu phosphating electrode was prepared by powder metallurgy and low temperature phosphating method. The phase, morphologic structure, and element distribution of the electrode were characterized by X-ray diffraction analysis (XRD), scanning electron microscope (SEM), and X-ray energy spectrum analysis (EDS). The electrocatalytic hydrogen evolution properties of phosphide electrode materials were tested by open-circuit potential (OCP), linear polarization curves (LSV) and electrochemical impedance spectrum (EIS). The res...
