چکیده انگلیسی
The visible-light activated In,S-TiO2@rGO nanocomposite was prepared using an innovative ultrasonic-assisted solvothermal method. The products were characterized by XRD, FT-IR, Raman, SEM, HRTEM, TGA and UV-Vis DRS. A considerable red shift in absorption edge of TiO2 was observed after co-doping with In and S. Co-doping of TiO2 with In and S elements and compositing with rGO significantly enhanced its visible-light photocatalytic activity. The complete degradation and 95.5% mineralization of 20â¯mg/L atrazine (ATZ) was attained at 3.0â¯mol% of In, 1â¯mol% of S and 5â¯wt% of rGO within 20â¯min. Reaction with OH at the surface of catalyst was the main mechanism contributed in degradation of ATZ in the developed photocatalytic process. As-made In,S co-doped TiO2@rGO nanocomposite could preserve its catalytic activity during four consecutive recycles for the ATZ removal process. The cytotoxicity of fresh and photocatalytic-treated ATZ solutions assessed using the human hepatic cells (HepG2) indicated that ATZ solution in the developed PCO process could be considerably detoxified.
