Fabrication Of N-doped TiO2/SnFe2O4/PANI Nanocomposites With Enhanced Photocatalytic Performances For Removal Of Organic Pollutants Under Visible Light

Nowadays, huge industrialization and uncontrolled growth of population have tremendously caused environmental contamination. Additionally, clean water resources are scarce[1]. Photocatalytic processes using semiconductors have caught eyes from a large number of researches as fascinating technology to endow environmental crisis [2]. For the first time, novel paramagnetic heterojunction photocatalyst N-TiO2-SnFe2O4-PANI with different PANI;TiO2 raitos were synthesized. This innovative photocartalyst merit from its high absorption of visible light and magnetic response that enable us to utilize much more spectra of radiation for more energy source and separate the catalyst from the media more easily. The catalytic activity of the as-prepared N-TiO2-SnFe2O4-PANI nanocomposite is investigated by the degradation of MO under visible light irradiation. As expected, the as prepared N-TiO2-SnFe2O4-PANI photocatalyst exhibit highly enhanced photocatalytic activity owing to fast separation of photo-generated electron-hole pairs and decompose MO up to 91.5% in 40 minutes. Significantly, no change in stability and degradation efficiency in separated catalyst from media has observed after 6 cycles uses.
