“…High intensity of peaks showed the excellent crystalline nature of WO 3 . 55 XRD pattern of FeV-WO 3 is almost identical to the WO 3 , although there is slight peak shiing to higher 2q values which may result from the contraction in lattice parameters aer the doping of Fe and V ions in parent lattice of WO 3 (Fig. 2(b)).…”

“…Organic pollutants in sewage such as azo dyes and antibiotics are hardly degraded, which are highly bio-toxic and easy to accumulate in the environment. Consequently, sewage is seriously threatening the life and health of humans, even destroying the ecosystem. − At the moment, advanced oxidation processes (AOPs) have been extensively studied because of their high activity and oxidation capacity for a wide range of pollutants . AOPs involve Fenton (or Fenton-like), − ozonation or catalytic ozonation, and persulfate (PS)-based AOPs .…”

Photocatalytic activation of persulfate has been receiving much attention in the field of wastewater treatment. In this work, the Bi 3 NbO 7 /BiOBr 0.75 I 0.25 nanosheet S-scheme heterojunctions were synthesized by the solvothermal method to activate persulfate. The degradation rates of rhodamine B (RhB) and TC by 0.05Bi 3 NbO 7 / BiOBr 0.75 I 0.25 were 95.4 and 74.7% in 2 h, respectively, indicating that 0.05Bi 3 NbO 7 /BiOBr 0.75 I 0.25 nanosheet heterojunctions have good photocatalytic activity. The synergistic effect between persulfate and the 0.05Bi 3 NbO 7 /BiOBr 0.75 I 0.25 photocatalyst was investigated under different persulfate contents, pH values, and light conditions. The RhB degradation rate of 0.05Bi 3 NbO 7 /BiOBr 0.75 I 0.25 activation persulfate is more than twice that of 0.05Bi 3 NbO 7 /BiOBr 0.75 I 0.25 , and the range of pH adaptation is wide. Radical quenching experiments showed that h + , • O 2 − , and •OH were the important active groups. Persulfate and catalysts produce a synergistic effect, which is S 2 O 8 2− reacting with e − to form •SO 4 − in the photocatalytic process. Meanwhile, the formation of •SO 4 − accelerates the process of photocatalytic reaction. This work provides ideas for the design of efficient and pollution-free photocatalysts for the activation of persulfate.

“…In the last ten years, visible light photocatalysis as an AOP has attracted considerable attention due to its potential applications for solving energy and pollution problems [13]. For the degradation of organic contaminants, materials like TiO 2 , ZnO, WO 3 , V 2 O 5 and ZnS are frequently used as photocatalysts [14][15][16][17]. They are unsuitable for visible light activity due to their wide bandgap energy.…”

The newly developed Z-Scheme Ni3V2O8/AgI visible light photocatalytic heterojunction composite system was fabricated using wet chemical technique with different weight percentages 10, 20, and 30% of Ni3V2O8 for the destruction of (RhB) Rhodamine-B. The purely isolated photocatalyst was further investigated through XRD, UV-vis DRS, TEM, FT-IR, PL, SEM, HRTEM, EDS, and photocurrent measurements. The Ni3V2O8/AgI nanocomposite degraded 82% of RhB with a higher reaction rate coefficient value of 0.0603 min–1 than the other synthesized photocatalysts. The results showed that Z-Scheme heterojunction formation has improved the partition and migration of charged particles leading to intensification in photocatalytic activity when compared to individual photocatalysts. The optimized 20% of Ni3V2O8 nanocomposite was reused three times without any change in photocatalytic performance, which confirmed the stability of the optimized nanocomposite photocatalyst Ni3V2O8/AgI. The outcomes of the radical trapping experiments suggested that radicals •OH and O2•− play a part in RhB degradation. Based on this, a visible light photocatalytic heterogeneous Z-Scheme mechanism is proposed. As a result, the newly fabricated Z-Scheme heterojunction Ni3V2O8/AgI photocatalyst could be a robust material for treating RhB water.
