Abstract

First demonstration of a gradient distributed oxygen vacancies (GO_V) strategy to promote hole transport within FeOOH. Clearly monitoring and verifying the progressive upward shift of the valence band within the shallow surface of FeOOH-GOv for enhancing holes transport capability. Setting new photoelectrochemical activity and stability benchmarks of FeOOH based-BiVO₄ photoanodes.
