“…The combination of photocatalysts with PVP results in the formation of nanocomposite materials, leading to a significant enhancement in photocatalytic performance. For instance, the BiOBr-PVP flower-like microsphere structure composite has demonstrated efficient degradation of 2,4-dichlorophenol [39], ofloxacin (OFL)/norfloxacin (NOR) [40], Cr (VI) [41], Rhodamine B (RhB), and diclofenac [42]. Zhiguo Zhang et al [43] demonstrated that the ultra-fine PVP-BiO 2−x nanomaterial, with a particle size distribution ranging from 5 to 10 nm, exhibited enhanced absorption capacity in the visible light spectrum.…”

FePMo12O40@PVP composite materials were synthesized with the regulation of polyvinylpyrrolidone (PVP) to control the structure. The samples were characterized by FT-IR, XRD, XPS, SEM, TEM and UV-Vis DRS. The composite retains the Keggin-type polyoxometalates structure, exhibiting a high specific surface area that enhances photon capture efficiency. Analysis of UV-Vis DRS absorption band edge and band gap indicated that the composite was responsive to visible light. Photocatalytic degradation of Rhodamine B (RhB) by FePMo12O40@PVP was investigated under commonly used LED light source, demonstrating excellent photocatalytic performance as 2.5 g-FePMo12O40@PVP (0.015 g) can remove 83% of RhB (10 mg/L) in 40 min. The FePMo12O40@PVP composite material demonstrated sustained moderate degradation efficiency even after undergoing three cycles of repeated use. The non-covalent interaction and strong interfacial coupling between PVP and FePMo12O40 promoted the transfer of h+, and e−, ∙O2−, ·OH, and h+ served as the primary active species in this photocatalytic system. This environmentally friendly material has the potential to significantly reduce energy consumption and offers valuable insights for the future treatment of dye wastewater.

BiOBr nanosheets were loaded onto SnO2 quantum dots, ZnO nanosheets, and SnO2/ZnO‐2 (SZ‐2) to form different heterojunction photocatalysts by sonochemistry, respectively. The photocatalytic activity of the prepared photocatalysts was evaluated by degrading the target dye Rhodamine B (RhB). The results showed that the degradation efficiency of BiOBr/SnO2/ZnO (BSZ) for RhB reached 97.5% at 80 min. The significant increase in catalytic activity of BSZ was attributed to the synergistic and interfacial effects among the three materials. Combined with the radical trapping experiments, it can be concluded that the catalytic mechanism of BSZ as a dual Z‐type heterojunction.
