In this research work, we reported the synthesis of a spherical-shaped bismuth vanadate (BiVO4) photocatalyst using a cost-effective, simple, chemical hydrothermal method and studied the effect of deposition temperatures on the structural, morphological, optical properties, etc The XRD result confirmed the monoclinic scheelite phase of BiVO4 An XPS study confirmed the occurrence of Bi, V, and O elements and also found that Bi and V exist in +3 and +5 oxidation states, respectively SEM micrographs revealed the spherical-shaped morphology of the BiVO4 photocatalyst Optical investigation showed that the bandgap of the BiVO4 photocatalyst varied between 225 and 232 eV The as-synthesized BiVO4 photocatalyst was used to study the photocatalytic degradation of crystal violet (CV) dye under visible light illumination The photocatalytic degradation experiment showed that the degradation percentage of crystal violet dye using BiVO4 reached 9821% after 120 min Mineralization of crystal violet dye was studied using a chemical oxygen demand analysisread more
