Giant Enhancement of Internal Electric Field Boosting Bulk Charge Separation for Photocatalysis

Incorporating carbon into Bi3O4Cl enhances its internal electric field by 126 times, which induces a bulk charge separation efficiency (ηbulk) of 80%. This ultrahigh ηbulk value presents a state-of-the-art result in tuning the bulk charge separation. The generated C-doped Bi3O4Cl has a noble-metal- and electron-scavenger-free water-oxidation ability under visible light, which is difficult to achieve with most existing photocatalysts.
