Abstract:
LaFeO3 films, as photoelectrocatalysts, could be slightly reduced by annealing in an oxygen-deficient atmosphere. The introduced oxygen vacancies increase the electrical conductivity and change their surface band structures which endows LaFeO3 films with a higher oxygen evolution reaction current and a lower overpotential.
