Novel magnetically recoverable BiOBr/iron oxides heterojunction with enhanced visible light-driven photocatalytic activity

- Novel magnetically recoverableBiOBr/iron oxides heterojunction were synthesized.
- BiOBr/iron oxides exhibited excellent photocatalytic activity under visible light.
- BiOBr/iron oxides displayed good magnetic separability and recyclability.
- The mechanism explained the improved photocatalytic performance.
