Application of ultrasonic irradiation method for preparation of ZnO nanostructures doped with Sb+3 ions as a highly efficient photocatalyst

- Ultrasonic irradiation method was applied for preparation of Sb-doped ZnO nanostructures in water at 60 min.
- The doping greatly changes morphology and size of the pure ZnO.
- The maximum photodegradation of methylene blue occurs with 0.03 Mol fraction of Sb+3 ions.
- The nanostructures have highest photocatalytic activity at pH 5.4.
