Prolonging Charge Carrier Lifetime via Intraband Defect Levels in S‐Scheme Heterojunctions for Artificial Photosynthesis

photoreduction with nearly 100 % CO selectivity in the absence of any photosensitizer or scavenger. Our work sheds light on the role of controllable defect levels in governing charge transfer dynamics within S-scheme heterojunctions, thereby inspiring the development of more advanced photocatalysts for artificial photosynthesis.
