Formatted abstract
The long-term stability and the effect of electrolysis on the corrosion behavior of porous Ni3Al–Mo electrode obtained by reactive synthesis of Ni, Al and Mo elemental powders for hydrogen evolution reaction (HER) were investigated in 6 M KOH solution under −100 mA cm−2 current density at room temperature. The long-term operation shows that the electrochemical activity of porous Ni3Al–Mo electrode increases slightly with increasing electrolysis time. The activation of electrode relates to the removal of the existing oxidation products during sintering process. The corrosion tests show that the corrosion resistance of the porous Ni3Al–Mo electrode changes after electrolysis.
