Preparation of nitrogen-doped titanium dioxide with visible-light photocatalytic activity of organophosphorus pesticide degradation

摘要

Adjusting the nitrogen content of N doped titania which were prepared by hydrothermal method to discuss the influences of the photocatalytic properties and the modifications. It was also established that N doped TiO2 powders enhances the Vis-light absorption. Finally the photocatalytic properties of catalysts were tested in the degradation of organophosphorus pesticide. The resulting materials were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), etc.
