Abstract

The oxygen evolution reaction (OER) is a vital half-reaction in several electrochemical energy conversion devices. Herein, we report a hierarchical NiMoO₄/NiFe LDH pre-catalyst that enables complete reconstruction and fine structural inheritance, while exhibiting a low overpotential of 188 mV at 10 mA cm⁻² in 1.0 M KOH.
