Abstract Oxygen vacancy (OV) defect engineering plays a crucial role in enhancing photocatalytic efficiency. However, the direct visual characterization of oxygen vacancies still remains technically limited. Herein, bismuth titanate (Bi 4 Ti 3 O 12 , BTO‐OV) model photocatalyst containing is constructed through density functional theory (DFT) calculations to reveal influence mechanism distinctive periodic quantum well and on charge transfer behavior BTO. Notably, distribution directly observed using low‐dose integrated differential phase contrast‐scanning transmission electron microscopy (iDPC‐STEM), providing evidence for location these BTO‐OV. Furthermore, theoretical calculation results are verified by characterizing photoelectric properties conducting performance tests hydrogen peroxide (H 2 ) photosynthesis. Specifically, BTO‐OV accelerate separation, leading H photosynthesis efficiency reaching 5278 µ m g −1 h which 5 times that original This work offers experimental references improvement mechanism.
