Abstract

In this study, walnut-shaped V2O3 particles with high photocatalytic activity in the visible light were synthesized by hydrothermal process. The V2O3 samples synthesized with the various temperature conditions of the hydrothermal process were characterized using XRD, SEM, TEM, UV-Visible spectrometer and N2gas adsorption/desorption analysis. For investigating the photocatalytic performance of synthesized V2O3 particles in the visible light condition, photodegradation experiments of methylene blue (MB) solution under artificial sunlight irradiation was conducted. As a result, the V2O3 hydrothermal-synthesized at 280 °C was composed of pure V2O3 crystal structure and showed high photocatalytic activity for the degradation of MB dye in visible light.
