Abstract

A simple anion-assisted cathodic co-electrodeposition method is used to prepare CeO₂-modified Mn₃O₄ nanoflakes on carbon cloth. The CeO₂ modifies the redox properties of Mn₃O₄ and enhances its intrinsic OER performance. It requires a low overpotential of 266 mV to reach 10 mA cm⁻² in 1.0 M KOH.
