Mn-incorporated nickel selenide: an ultra-active bifunctional electrocatalyst for hydrogen evolution and urea oxidation reactions

Abstract

We report Ni–Mn–Se supported on Ni foam as a highly active and stable bifunctional electrocatalyst that exhibits overpotentials of 28 and 122 mV to reach a current density of 10 mA cm−2 for the hydrogen evolution reaction (HER) and urea oxidation reaction (UOR), respectively, and maintains its stability for over 50 h in both reactions. In addition, an overall urea splitting cell voltage of 1.352 V is needed at the current density of 10 mA cm−2 for the optimized electrode.
