Abstract

In this work, pure TiO2 and nano-magnetic of Fe3O4/TiO2 were synthesized for degradation of 2,4-dichlorophenol (2, 4-DCP) as an organic pollutant. A range of analytical techniques including XRD, DRS, FESEM, and VSM were employed to reveal the crystal structure, morphology and property of the nanocomposite. The XRD results showed the prepared samples including 100% anatase phase. We obtained the band gap energy 2.9 and 2.8 eV for pure TiO2 and Fe3O4/TiO2 respectively. VSM results demonstrate that easy, fast separation and redispersion of Fe3O4/TiO2 sample can be realized. We obtained 62% and 31% degradation of 2,4-DCP in the presence of  Fe3O4/TiO2  and pure TiO2 under visible light respectively.
