Sono-synthesis of bismuth ferrite nanoparticles with high photocatalytic activity in degradation of Rhodamine B under solar light irradiation

- BiFeO3 was synthesized in mild conditions with ultrasound.
- Rhodamine B was completely destroyed in 35 min under sunlight irradiation.
- Complete mineralization was achieved in 90 min.
- BiFeO3 had no significant loss of activity even after four cycles of uses.
- Hole had a main role in photocatalytic degradation of RhB.
