Abstract

One of the most difficult problems of elimination colors from industrial effluent utilizing visible-light. Due to its small bandgap, vanadium pentoxide (V2O5) is receiving a lot of attention as a potential visible light for the breakdown of organic contaminants. However, the V2O5 catalyst's quick electron-hole pair recombination restricts its use in photo-degradation. The performance of V2O5 as a photo catalyst can be enhanced by interacting with other semiconductors. In this study, we used a hydrothermal approach to prepare V2O5/ZnO nanocomposites. Using characterization methods like (FE-SEM), (EDX), X-ray diffraction (XRD), the physical characteristics of the as-synthesised products were investigated. The creation of pure ZnO, V2O5 nanoparticles and the presence of diffraction peaks associated with the hexagonal phase of ZnO, orthorhombic V2O5 were both confirmed by the XRD data. The Scherer equation was used to analyze the variance in structural characteristics. The nanocomposite's computed energy bandgap (2.63 eV) from UV-vis spectroscopy suggested that it might be used as a photo catalyst under a UV-visible light. The ZnO/ V2O5 nanocomposite production was also confirmed by FTIR spectra. FE-SEM images revealed spherical and approximately hexagonal shape. The nanocomposite contains Zn, V, and O, according to EDX examination. Photocatalytic degradation of the ZnO/ V2O5 nanocomposite to removal GRL dye (59.52%).
