Oxygen vacancy modulated Fe-doped Co 3 O 4 hollow nanosheet arrays for efficient oxygen evolution reaction.

Published in: Chemical communications (Cambridge, England) (2024)

Herein, Fe-doped Co 3 O 4 hollow nanosheet arrays with rich oxygen vacancies (V o -Fe-Co 3 O 4 ) are constructed using a facile strategy. Benefiting from the compositional and structural superiorities, V o -Fe-Co 3 O 4 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.
