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.
