Abstract
Nitrogen doped anatase TiO 2 (N-TiO 2) were prepared by hydrothermally treating TiN with H 2O 2. The as-synthesized samples were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), UV–vis diffuse reflectance spectrum (DRS), Fourier transform infrared spectra (FT-IR) and X-ray photoelectron spectroscopy (XPS) techniques. The results confirmed that the hydrothermal oxidation is an effective method to prepare N-doped TiO 2 anatase. The nitrogen concentration in TiO 2 could be controlled by the concentration of H 2O 2 solution. Photocatalytic degradation of methyl orange (MO) was carried out under visible light and UV–visible light irradiation, respectively. The as-prepared optimal N-TiO 2 showed higher photocatalytic activity than N-P25 and P25, and exhibited excellent reusability.
