| Abstract: | A Ni-Mo/LaNi5 porous composite electrode was successfully prepared by composite electrodeposition and dissolution with a concentrated alkali solution. We found that the electrode consisted of two phases and a porous structure using scanning electron microscopy (SEM) and X-ray diffraction (XRD). In a 20% (w) NaOH solution the electrocatalytic properties toward hydrogen evolution reaction (HER) of the electrode was evaluated using electrochemical steady-state polarization curve and electrochemical impendence ... |
