Abstract

In this work, high-performance Ni-Zn/CeO₂composite electrodes are prepared for hydrogen evolution reaction (HER) in alkaline solutions using a composite electrodeposition technique in a Ni-Zn bath containing suspended micro- or nano-sized CeO₂particles. The composite electrodes containing more CeO₂particles are dominant with laminate morphology. The addition of CeO₂particles can alter the electrode phase composition. Optimization of the concentration of CeO₂particles leads to a significant enhancement of HER activity on the composite electrodes, relative to Ni-Zn coating. The exchange current density of the composite electrode is 2 times higher than that of the Ni-Zn coating when the nano-CeO₂concentration is 1 g L^-1. Electrochemical impedance spectroscopy results suggest that a possible synergetic effect on HER may exist between CeO₂particles and Ni-Zn matrix.
