Semiconductor photocatalysis, heterogeneous photo-Fenton and photocatalytic persulfate activation are light-driven advanced oxidation processes (AOPs) that have attracted much attention as promising technologies in wastewater treatment. Nevertheless, their large-scale application still faces several challenges, including the need to separate catalyst from treated water. In this regard, composite catalysts made up of semiconductor magnetic materials been understood a potential alternative since resulting photocatalysts can be easily separated medium by applying an external field. Interestingly, apart facilitating photocatalyst retrieval, components could also involved process. However, while separation ability has widely highlighted, other functions constituents remain obscure. This work, which covers last 6 years research, provides comprehensive review on magnetically assisted degradation organic pollutants Specifically, commonly employed for purpose presented different roles (roughly grouped retrieval assistance, active catalyst, conduction or activator) discussed. Furthermore, importance designing separators attaining is emphasized. Collectively, study supply avenue developing take advantage both materials, contribute accomplish more efficient pollutant degradation.
