| Description | Different tri-doped $TiO_{2}$ photocatalysts $(Fe-N-P/TiO_{2}$, $Fe-N-S/TiO_{2}$, $Fe-Pr-N/TiO_{2}$, $Pr-N-S/TiO_{2}$, and $P-N-S/TiO_{2}$) were successfully prepared and tested in the photocatalytic removal of thiacloprid (THI) under UV-A, visible, and direct solar light irradiation. The physical-chemical properties of the prepared catalysts were analyzed by different characterization techniques, revealing that dopants are effectively incorporated into the anatase $TiO_{2}$ lattice, resulting in a decrease of the energy band gap. The reduction of photoluminescence intensity indicates a lower combination rate and longer lifespan of photogenerated carriers of all doped samples in comparison with the un-doped $TiO_{2}$. The doped photocatalysts not only significantly promote the photodegradation under UV-A light irradiation but also extend the optical response of $TiO_{2}$ to visible light region, and consequently improve the visible light degradation of THI. Fe-N-P tri-doped $TiO_{2}$ sample exhibits the highest THI photodegradation degree (64% under UV-A light, 29% under visible light and 73% under solar light). |
