Abstract

Herein, Fe-doped Co₃O₄ hollow nanosheet arrays with rich oxygen vacancies (V_o-Fe–Co₃O₄) are constructed using a facile strategy. Benefiting from the compositional and structural superiorities, V_o-Fe–Co₃O₄ exhibits a remarkable OER overpotential of 231 mV at 10 mA cm⁻² and a Tafel slope of 57.45 mV dec⁻¹ in an alkaline medium.
