Abstract
characterization during the electrocatalytic process reveals the gradual transformation of the metal center into metal hydroxyl oxides upon increasing the voltage to 1.55 V. DFT analysis suggests that in the Fe-Ni double site reaction pathway, active substances preferentially adsorb on the Fe site before the Ni sites.
