“…Photoelectrochemical characterization results display that the V2O5/g-C3N4/ZnO photocatalytic nanocomposite improves photogenerated charge separation efficacy more than ZnO, g-C3N4, and V2O5. These results show that the separation along with transfer effectiveness of photogenerated electron-hole pairs increased, as demonstrated by these results, affirmed the higher photocatalytic ability observed the V2O5/g-C3N4/ZnO nanocomposite had [54,55].…”

In the present research investigation, a novel nanocomposite viz. V2O5/g-C3N4/ZnO was synthesized using wet impregnation technique. Its photocatalytic degradation performance was assessed against various organic pollutants including the antibiotic Amoxicillin (AMX), the pesticide Chlorpyrifos (CPF), and the dye Methylene Blue (MB), under the effect of visible light in an aqueous medium. The materials synthesised and their photodegradation effectiveness were systematically characterized by a variety of techniques including XRD, HR-SEM, TEM, EDS, XPS, UV-DRS, PL, BET, and EIS. XRD spectra confirmed the existence in the hexagonal phase of g-C3N4, the hexagonal wurtzite structure in ZnO, and the orthorhombic phase in V2O5. The corresponding plane in the V2O5/g-C3N4/ZnO nanocomposite was also identified. The HR-SEM images depicted a composite of nanosheets and nanorods within the nanocomposite. The synthesized photocatalyst revealed an effective visible light absorption with a bandgap of 2.5 eV and displayed remarkable photocatalytic degradation efficiencies of 93.23% for MB, 62.02% for CPF, and 55.36% for AMX when exposed to visible light for 90 minutes. This proved its higher efficiency than that of individual components viz. g-C3N4, ZnO, and V2O5. The hydrogen ions (h+) and superoxide ions (O2•−) were found to be the key reactive species, which are involving in the photodegradation process by radical scavenging tests. Furthermore, the present nano photocatalyst proved its remarkable photocatalytic stability even after three cycles, showing its favorable chemical properties. The findings imply that this reported photocatalyst is highly suitable for efficiently photodegrading the organic pollutants in aqueous environments.

“…Rajarajan and coworkers developed a facile in situ oxidative polymerization strategy to construct a novel V 2 O 5 /G-C 3 N 4 /PVA electrode material for the detection of folic acid. 38 It was demonstrated that the V 2 O 5 /G-C 3 N 4 /PVA/GCE can display superior electrocatalytic activity toward folic acid detection. According to a series of characterizations and experimental tests, it was revealed that the introduction of PVA can greatly improve the electrical conductivity of a modified electrode, which significantly facilitated electron transfer during electrochemical reactions.…”
