Oxygen vacancy modulated Fe-doped Co3O4 hollow nanosheet arrays for efficient oxygen evolution reaction†
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.
