An Updated Overview of Magnetic Composites for Water Decontamination

“…Moreover, magnetite nanoparticles exhibit thermal, chemical, and colloidal stability; dispersibility; and functionalization possibility-advantageous features that extend their versatility [42]. Other ferrites that showed good promise in environmental purification applications include barium hexaferrite (BaFe12O19; excellent electrical, magnetic, optical and photocatalytic properties; remarkable stability; and reusability) [43][44][45], strontium hexaferrite (SrFe12O19; high saturation magnetization, great stability, and excellent photocatalytic properties) [46], and lead hexaferrite (PbFe12O19; high saturation magnetization, coercivity, catalytic activity, and stability) [47,48].

Solid-waste-recycled CuO/C3N4 S-scheme heterojunctions for efficient photocatalytic antibiotic degradation

“…23 By forming an internal electric field between an oxidation catalyst and a reduction catalyst, the S-scheme heterojunction can not only ensure the effective carrier separation of both catalysts, but also improve their redox capability. 24–26 Among the common photocatalysts, C 3 N 4 has garnered significant attention due to its narrow band gap, suitability for visible light absorption, facile synthesis, excellent thermal stability, and robust acid and alkaline resistance. 27–32 Although the narrow band gap of C 3 N 4 brings a good visible light absorption capacity, it restricts the redox capacity of C 3 N 4 .…”

A novel CuAl2O4/MoS2/BaFe12O19 magnetic photocatalyst simultaneously coupling type I and Z-scheme heterojunctions for the sunlight-driven removal of tetracycline hydrochloride

“…Hexagonal barium ferrite (BaFe 12 O 19 , BFO) is a kind of strong magnetic material that not only has strong magnetic properties but also has a wide range of applications in the field of photocatalytic degradation of dyes and other pollutants. 37–46 A CAO/MS/BFO magnetic photocatalyst that is coupled with CAO, MS, and BFO can effectively resolve the difficult recovery and improve the photocatalytic activity of CAO/MS photocatalyst due to the Z-scheme heterojunctions formed by introducing BFO to a type I CAO/MS photocatalyst. It is of great significance to develop new synthesis routes to synthesize the CAO/MS/BFO magnetic photocatalysts and study their photocatalytic activities.…”
