摘要：

Highly efficient visible-light catalysts are achieved through forming defectpairs in TiO2 nanocrystals. This study therefore proposes that fine-tuning the chemical scheme consisting of chargecompensated 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.
