Abstract

The alkaline electrolyzer fabricated by employing Co@CoO core-shell nanoparticles on N-doped graphene as bifunctional catalysts exhibits remarkable activity with a current density of 10 mA cm-2at a cell voltage of 1.58 V and considerable stability over 8 h of continuous electrolysis operation at 100 mA cm-2, favorably comparable to the integrated performance of Pt and IrO2.
