FE3O4 DECORATED TIO2 NANO TUBE PHOTO CATALYST SEMICONDUCTOR

Abstract

Fe 3 O 4 -TiO 2 nanocomposite photocatalyst with different weight percentage (5, 10, and 15 wt %) of Fe 3 O 4 loaded On TiO 2 were successfully synthesized by co-precipitation method for removal of methylene blue dye under direct sunlight. The characterization of the as prepared product was done with scanning electronic microscopy (FE-SEM), X-ray diffraction (XRD), and Diffuse reflectance spectra (DRS). The photocatalytic degradation of methylene blue was used as modal reaction to evaluate the photocatalytic activity of Fe 3 O 4 @TiO 2 nanoparticles under visible light irradiation . The influence of doping amount of Fe 3 O 4 (5, 10, 15 wt% ) on photocatalytic activity of TiO 2 was investigated. Broadened absorption spectra has describe that the size of Fe 3 O 4 @TiO 2 particle decreased with increased absorption intensity. The doping amount remarkably affects the activity of the catalyst, and the optimum efficiency occurs at about the doping amount of 10 wt%. The catalytic activity of TiO 2 increased for methylene blue (MB).
