Abstract

Abstract In this report, the photodecolorization of Congo red pigment by V2O5–TiO2 nanohybrid was analyzed. Sonication approach was employed to produce V2O5–TiO2 nanohybrid materials. X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), high-resolution electron microscopy (TEM), BET-surface rea analyzer, and UV spectroscopy were utilized to describe the V2O5–TiO2 nanohybrid materials. Meanwhile, the photocatalytic behavior, pH, and reactive oxygen are examined in detail to explain CR pigment decolorization. Congo red pigment photodestruction exhibited a rate constant of 0.03567 (min−1) and a decolorization rate of 96%. The degradation efficiency of Congo red pigment by V2O5–TiO2 catalysts follows the pseudo-first-order kinetics assumption. The findings of this work displayed that V2O5–TiO2 act as a highly efficient nanocatalyst for destroying pigments in water.
