Fabrication of magnetic dual Z-scheme heterojunction materials for efficient photocatalytic performance: The study of ternary novel MIL-88A(Fe)/BiOBr/SrFe12O19 nanocomposite

•A dual Z-scheme MBSr ternary composite was developed.•The dual Z-scheme heterojunction enhanced visible-light adsorption and the transfer of photoinduced charged carriers.•The photocatalytic performance of MBSr is superior to that of single and binary composites.•Possible photodegradation pathway and mechanism of RhB were proposed.
