Electrocatalytic Behavior of Ni-S-Mn Alloy Electrode for Hydrogen Evolution Reaction
Abstract:
The alloy electrode of amorphous Ni-S-Mn electrodeposited on the surface of nickel net and used in water electrolysis was prepared and studied.The electrocatalytic activity of Ni-S-Mn electrode for hydrogen evolution reaction was evaluated by means of cathodic polarization curves and related electrochemical parameters.The results show that the overpotential of hydrogen evolution reaction is 180 mV and 80 mV less than Ni and Ni-S electrodes,respectively.This illustrates that the electrocatalytic activity of so-prepared Ni-S-Mn electrode is better than those of Ni and Ni-S electrodes.The potential scan with a small-amplitude triangular wave,SEM,TEM and XRD methods were applied to the analyses of the roughness,morphology and microstructure of the electrode surface.Finally,the role of element Mn was discussed in detail.
