| 摘 要： | N-doped TiO2 （N-TiO2） nanoparticles were synthesized via a one-step low temperature （180℃） solvothermal route, which adopted NH4NO3 as the nitrogen source. The structure, composition, BET specific surface area, and optical properties of the as-synthesized product were characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, N2 adsorption- desorption isotherms, and UV-vis diffuse reflectance spectroscopy. In addition, its photocatalytic properties were tested by the reduction of aqueous Cr（VI） under UV and visible light （x 〉 420 rim） irradiation. It was observed that for the reduction of aqueous Cr（VI）, the as-synthesized N-TiO2 nanoparticles not only exhibited much higher photocatalytic activity than P25 TiO2 under UV light, but also exhibited remarkably high photocatalytic activity under visible light （λ 〉 420 nm）.
