This study therefore proposes that fine-tuning the chemical scheme consisting of charge-compensated defect-pairs in balanced concentrations is a key missing step for realizing outstanding photocatalytic performance. This research benefits photocatalytic applications and also provides new insight into the significance of defect chemistry for functionalizing materials.Q.S., D.Co., T.J.F. and Y.L. acknowledge the support of the Australian Research Council (ARC) in the form of Discovery Projects.
