Elimination of BPA endocrine disruptor by magnetic BiOBr@SiO2@Fe3O4 photocatalyst

- BPA was eliminated by magnetic BSF photocatalyst under visible light irradiation.
- Both h+ and ·OH were proved to be active species in the photoreaction with BPA.
- Possible pathways for BPA decomposition were proposed.
- The BSF photocatalyst was superior to that of P25 even under UV light irradiation.
- The BSF photocatalyst can be efficiently recycled in 60 s.
