Synthesis of ZnO Nanoparticles and Its Photocatalytic Application

Abstract

ZnO nanoparticles as photocatalyst were synthesized by a simple synthetic route involving hydrothermal method at 150°C, and it is efficiently characterized by number of techniques, such as XRD, FESEM, and UV-vis DRS. UV-vis DRS and showed a reflection edge with corresponding energy at 3.5 eV. The photocatalytic removal activity of the ZnO nanoparticles was tested against the removal of MB dye under natural sunlight irradiation. About 75% degradation of methylene blue is observed in 150 min.
