Oxygen Vacancy‐Rich S‐Scheme Heterojunction Photocatalyst With Enhanced Interfacial Charge Transfer for Round‐the‐Clock Formaldehyde Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work addresses the critical challenges of severe charge recombination and the dependence on constant light illumination in photocatalysis. We propose a strategy centered on an oxygen vacancy‐rich S‐scheme heterojunction, which enables precise regulation of charge carrier behavior and achieves long‐lasting photocatalytic performance.
