Effect of Ag Doping on ZnO/V 2 O 5 Nanoparticles as a Photo Catalyst for the Removal of Maxillion Blue (GRL) Dye

In this research, the photo catalytic degradation of textile dyes as a model Maxillion Blue (GRL) dye by using Ag/ZnO/V₂O₅ nanocomposites synthesised via hydrothermal method. The physical properties of the as-synthesised nanocomposites were examined using characterisation techniques such as scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), TEM, and UV-vis spectroscopy. the production of pure ZnO, V₂O₅ nanoparticles and the discovery, by XRD analysis, of diffraction peaks related to the hexagonal phase of ZnO, V₂O₅, UV-vis spectroscopic calculations of the nanocomposite’s energy bandgap (2.63 eV) indicated that it might function as a photo catalyst when exposed to UV-visible light. XRD also supported the fabrication of the ZnO/V₂O₅ nanocomposite. FE-SEM images showed that the object was spherical and somewhat hexagonal in form. EDX analysis reveals the presence of Zn, V, and O in the nanocomposite; its photocatalytic activity was evaluated through the degradation of GRL dye under exposure to solar light. The results showed that the optimum mass nanocomposite for efficient photo degradation was 0.4 g/L, with a degradation efficiency of 91.6%.
