Ni-Fe/TiO2 composite electrodes were prepared by electrodeposition.Cathodic polarization curve and electrochemical impedance spectroscopy were used to study the hydrogen catalytic property of electrodes.The results show that the hydrogen evolution property of Ni-Fe/TiO2 composite electrode is better than Ni-Fe alloy electrode.TiO2 particles can increase specific surface area of electrode,Ti can form Ti-Hads hydrogen bond with H,which is favorable for formation and adsorption,a composite desorption effect of Hads exists between TiO2 particles and Ni-Fe alloy,enhancing hydrogen catalytic performance of electrode.With the addition of TiO2 particles in the bath,the catalytic performance for hydrogen evolution of electrode first increases and then weakens.
