摘要：

Designing a semiconductor semiconductor junction as photocatalyst to reduce the recombination efficiency of photogenerated charges for enhanced photocatalytic activity has become an effective method. Here, magnetic BiOBr-NiFe2O4 hybrids were prepared by a facile chemisorption method and characterized by XRD, TEM, XPS and DRS. BiOBr nanosheet is distributed on NiFe2O4 phase with identical morphology constructing a firm heterojunction. Compared with the pure NiFe2O4, 25% BiOBr-NiFe2O4 composite exhibits excellent photocatalytic performance for RhB degradation under visible light illumination, which is owing to the fast separation of electron-hole pairs in the heterojunction interface. The magnetic quality of composites can be a great advantage over other non-magnetic materials for catalyst recycling.
