Synthesis of Nitrogen and Sulfur Codoped TiO2 and its Better Efficient Degradation of Organophosphorus Pesticides
N, S codoped titania with high photocatalystic properties were prepared by hydrothermal method. The resulting materials were characterized by X-ray diffraction, X-ray photoelectron spectroscopy. N, S codoped titania displayed a better degradation rate of organophosphorus pesticide under visible light irradiation. The utility of N, S codoped TiO2 as a photocatalysis over undoped titania entirely, whether the requirement for visible-light functionality, even if at low efﬁciency, outweighs a modest drop in the efﬁciency of catalysis using UV light.
