- •
PO4-doped Bi2WO6 is firstly prepared by the urea-precipitation method, which exhibits the enhanced photocatalytic activity for removing various contaminants in water.
- •
Doping effect of PO4 group effectively adjusts band gap and increases the separation efficiency of charge carriers.
- •
This work launches an exemplificative strategy for doping ionic group into the Bi-based oxides to improve photocatalytic activity.
