Ionic liquid-induced strategy for carbon quantum dots/BiOX (XÂ =Â Br, Cl) hybrid nanosheets with superior visible light-driven photocatalysis

- A one-step ionic liquid induced strategy for the synthesis of CQDs/BiOX nanosheets.
- The 3 wt% CQDs/BiOBr nanosheets showing the highest photocatalytic activity.
- The hole and O2− are the dominant species for the degradation of pollutants.
