| Abstract: | Nitrogen doped TiO_ 2 nanosize particles were prepared under hydrothermal condition with tetra-n-butyl titanate and ammonia as the precursors.The products obtained under different conditions were characterized by means of X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS) and ultraviolet-visible diffuse reflection spectrum(UV-Vis DRS). The influences of various proportion by volume, hydrothermal temperature, hydrothermal time and calcination temperature to the structure and activities of catalysts were investigated. Photocatalytic activities of the nitrogen doped catalysts were evaluated under ultraviolet and visible light irradiation by photodegradation of methylic-orange and phenol respectively. |
