Photocatalytic Degradation of Thiacloprid Using Tri-Doped TiO2 Photocatalysts: A Preliminary Comparative Study
نویسندگان
چکیده
Different tri-doped TiO2 photocatalysts (Fe-N-P/TiO2, Fe-N-S/TiO2, Fe-Pr-N/TiO2, Pr-N-S/TiO2, and P-N-S/TiO2) were successfully prepared tested in the photocatalytic removal of thiacloprid (THI) under UV-A, visible, direct solar light irradiation. The physical-chemical properties catalysts analyzed by different characterization techniques, revealing that dopants are effectively incorporated into anatase lattice, resulting a decrease energy band gap. reduction photoluminescence intensity indicates lower combination rate longer lifespan photogenerated carriers all doped samples comparison with un-doped TiO2. not only significantly promote photodegradation UV-A irradiation but also extend optical response to visible region, consequently improve degradation THI. Fe-N-P sample exhibits highest THI degree (64% light, 29% 73% light).
