Selenization of NiMn-layered double hydroxide with enhanced electrocatalytic activity for oxygen evolution

Author affiliations

Abstract

Exploiting highly active oxygen evolution reaction electrocatalysts is of great importance in the cost-effective generation of clean fuels. Herein, the preparation of NiMn-layered double hydroxide with selenization is adopted to reduce the charge transfer resistance of the electrocatalytic oxygen evolution reaction and enhance electrocatalytic performance. As a result, this selenization product of NiMn-layered double hydroxide can reach a current density of 10 mA cm−2 at a low overpotential of 280 mV on glassy carbon electrode in 1.0 M KOH aqueous solution and have excellent stability, which makes them comparable to the most efficient IrO2 catalyst and better than most nickel based catalysts.
