Bisphenol S-doped g-C3N4 nanosheets modified by boron nitride quantum dots as efficient visible-light-driven photocatalysts for degradation of sulfamethazine

Effects of Sulfamethazine and Cupric Ion on Treatment of Anaerobically Digested Swine Wastewater with Growing Duckweed

“…Pathway 3 commonly includes the scission of S-N bonds. The S-N bond was cleaved to constitute P5 and P8, and next P8 was changed to P7 by oxidation reaction [ 27 ]. In the end, the formed degradation products P4, P5, and P7 can be further mineralized into small molecules, such as water and carbon dioxide [ 46 ].…”

“…The following gradient was used: 0–12 min, 10% B to 60% B; 12–14 min, 60% B to 95% B; 14–16 min, 95% to 10% B; 16–17 min, 10% B. The instrument parameter settings were described by Zhang et al [ 27 ]. In addition, the concentration of SMZ was determined by HPLC (Agilent, Waldbronn, Germany), which was furnished a UV–vis detector.…”

In situ synthesis of holey g-C3N4 nanosheets decorated by hydroxyapatite nanospheres as efficient visible light photocatalyst

“…Other works have also shown that the g-C 3 N 4 nanocomposite produced more oxygen radicals under light irradiation in comparison to single g-C 3 N 4 . 53 Generally, it can be highlighted that carbon-based materials, such as g-C 3 N 4 or carbon nanotubes could inuence the production of more active radicals due to spatial separation of photogenerated charges. 54,55 Electron paramagnetic resonance (EPR) analysis at room temperature indicated that the holey structure bears heavily delocalized electrons, which led to a high separation of photoinduced charge pairs.…”

Coatings of magnetic composites of iron oxide and carbon nitride for photocatalytic water purification

“…3,10,15,[20][21][22][23][24] Doping and exfoliation was demonstrated to enhance the degradation efficiencies of CN materials and alternatively the combination with other semiconductors was demonstrated to be successful. 12,[25][26][27] Selected examples for CN composites comprise MoS 2 /C 3 N 4 , Bi 2 WO 6 /C 3 N 4 , Ag/C 3 N 4 , Fe 3 O 4 /C 3 N 4 and a-Fe 2 O 3 /C 3 N 4 . 12,15,22,28,29 However, these investigations are based on dispersions of particles, and their use requires an additional costly process step for particle separation in any technologically relevant approach.…”
