Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

Advanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.
