- •
A ionic liquid induced strategy for the synthesis of ultrathin C3N4/Bi4O5I2 nanojunctions.
- •
The introduction of reactable ionic liquid was used for the formation of ultrasmall Bi4O5I2 nanosheets and the improvement of the dispersity of ultrathin C3N4, which contributed to the combination of ultrathin C3N4 and Bi4O5I2 together efficiently and further favor the construction of tight junction between the two.
- •
The 3 wt% C3N4/Bi4O5I2 nanojunctions exhibit the highest photocatalytic activity for removing the RhB and BPA in solution.
- •
The hole is the dominant species for the degradation of pollutants.
