Persulfate Activation of Photocatalysts Based on S-Scheme Bi3NbO7/BiOBr0.75I0.25 Nanosheet Heterojunctions for Degradation of Organic Pollutants

“…Furthermore, the diffraction peak of Bi 3 NbO 7 moves to the right and that of BioBr 0.75 I 0.25 moves to the left. According to Bragg’s formula, the increase of Bi 3 NbO 7 doping significantly changes the distance between the layers, indicating that an interface interaction between Bi 3 NbO 7 and BiOBr 0.75 I 0.25 is formed (Figure b). , …”

“…In Figure c,d, the characteristic peaks of ·O 2 – ·OH, and ·SO 4 – did not appear in the dark reaction condition and ·O 2 – and ·OH appeared in both systems after illumination. However, only ·SO 4 – appeared in the system adding PS, indicating that the adsorption in the dark reaction could not produce effective active groups and ·SO 4 – was generated by the reaction of PS with a heterojunction …”

“…According to Bragg's formula, the increase of Bi 3 NbO 7 doping significantly changes the distance between the layers, indicating that an interface interaction between Bi 3 NbO 7 and BiOBr 0.75 I 0.25 is formed (Figure 1b). 42,43 The morphology and structure of Bi 3 NbO 7 , BiOBr 0.75 I 0.25 , and 0.05NO-BOBI were expounded in SEM, TEM, and HRTEM images (Figure 2). Bi 3 NbO 7 is cube-shaped and approximately 53.74 nm in average grain diameter (Figure 2a,d, Figure S2).…”

Insights into Fenton-like oxidation of oxytetracycline mediated by Fe-doped porous g-C3N4 nanomaterials: synthesis, performance and mechanism

“…Ma et al synthesized Fe and Ti co-doped g-C 3 N 4 to achieve an excellent performance for the degradation of OTC (0.05028 min −1 ). 12 Liu et al designed bio-inspired SACs by inserting pyrrole-type Fe-N 4 single sites into g-C 3 N 4 , which presented high tolerance to pH changes and low consumption of H 2 O 2 . 13 In addition, the catalytic activity also relies on a large specific surface area.…”

A hydrangea-like nitrogen-doped ZnO/BiOI nanocomposite for photocatalytic degradation of tetracycline hydrochloride

“…[5][6][7] Among these technologies, the photocatalysis, one of the advanced oxidation processes (AOPs), has been attracting considerable attention due to its pollution-free, ecofriendly and efficiency. [8][9][10][11] However, the most conventional photocatalysis can only use ultraviolet light, which accounts for only 5% of the sunlight, 12 such as TiO2. To improve the utilization of light, there is an increasing emphasis on photodegradable materials that can be used to operate under visible light.…”
