Abstract:
Herein, Fe-doped Co3O4 hollow nanosheet arrays with rich oxygen vacancies (Vo-Fe-Co3O4) are constructed using a facile strategy. Benefiting from the compositional and structural superiorities, Vo-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.
