Abstract

Porous Ni3Al–Mo electrodes were obtained by reactive synthesis methods with Mo contents of 2, 5, 10, 15 and 20 wt-% respectively. The microstructure, surface morphology and composition of the prepared porous Ni3Al–Mo electrodes were analysed by X-ray diffraction (XRD), X-ray photoelectron spectrometry (XPS) and scanning electron microscopy (SEM). Hydrogen evolution reaction (HER) on the porous Ni3Al–Mo electrodes in 6 mol L−1 KOH solution was investigated by polarisation measurements and electrochemical impedance spectroscopy (EIS) technique. It was shown that the hydrogen evolution activity of the porous Ni3Al–Mo electrodes was related with the Mo content. The porous Ni3Al–Mo electrode with optimum catalytic activity for the HER was found to contain the maximum Mo content of 10 wt-%.
