Abstract
In this study, B1VO4 photocatalysts have been successfully synthesized by hydrothermal method and were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), UV-Vis diffusion reflectance spectra (UV-Vis DRS), and Raman spectroscopy. From XRD, Raman, and UV-Vis DRS results, the as-synthesized B1VO4 showed monoclinic scheelite structure and narrow band gap energy (Eg = 2.35 eV). The morphology of as-prepared powder showed a small crystallite size with different shapes. The photocatalytic performances of the as-prepared sample were evaluated by the degradation of sulfamethoxazole under visible light. Also, H2O2 was added to enhance the photocatalytic activity of BiVO4. It has been noticed that 70% photodegradation of antibiotic occurs on the catalyst surface with visible light irradiation. Besides, the effects of pH and organic salts are also discussed in this study.
