Construction of Te-ZnO@S-g-C3N4 Heterojunction Nanocomposites for the Efficient Removal of Methylene Blue, Antifungal Activity, and Adsorption of Cr(VI) Ion

Heterojunctions have proven to be effective catalysts for removing organic pollutants and heavy metals from wastewater. The following study is also about the formation of 2D heterojunction tellurium-doped zinc oxide composite with sulfur-doped graphitic carbon nitride (Te-ZnO@S-g-C3N4) by adopting a low-cost, simple, ecofriendly coprecipitation technique. Thiourea was calcined prepare S-g-C3N4 using thermal degradation method. characterization synthesized photocatalysts carried out SEM-EDX, FTIR, XRD. results obtained showed that incorporation tellurium caused an alteration in wurtzite structure ZnO. SEM-EDX analysis validated purity samples due absence any additional peaks. decrease bandgap noted composites. Using methylene blue as reference dye, UV-vis spectrophotometer utilized calculate absorbance photocatalytic behavior. As result doping into ZnO lattice, oxidation/reduction improved, according results. 3Te-ZnO NPs best rate among dopant series, while excellent overall fabricated 3Te-ZnO@40S-g-C3N4. doped composites were used sorbents abstraction metal (Cr(VI)) water via adsorption. A definite rise removal efficiency percentage chromium ions observed these sorbents. photo adsorption behavior ZnO<Te-ZnO<Te-ZnO@S-g-C3N4 order. When compared ZnO, Te-ZnO, SCN, Te-ZnO@40SCN, 3Te-ZnO@40SCN NCs outstanding antifungal potential. improved dispersibility interaction membrane intracellular proteins fungi may cause greater effect Te-ZnO@40SCN.
