Incorporating carbon into Bi 3 O 4 Cl enhances its internal electric field by 126 times, which induces a bulk charge separation efficiency ( η bulk ) of 80%. This ultrahigh η bulk value presents a state‐of‐the‐art result in tuning the bulk charge separation. The generated C‐doped Bi 3 O 4 Cl has a noble‐metal‐ and electron‐scavenger‐free water‐oxidation ability under visible light, which is difficult to achieve with most existing photocatalysts.
