摘要：
The hydrothermal preparation process of N-doped TiO2 was optimized to enhance photocatalytic activity under visible irradiation by the response surface methodology. The results indicated that calcination temperature was the main factor for N-doped TiO2 preparation. The maximum methylene blue removal efficiency of 95.6% was achieved at pH 6.05, calcination time 6.87 h and calcination temperature 403 degrees C. Fourier transform infrared and X-ray photoelectron spectroscope spectra both confirmed that N-doped TiO2 calcined at 400 degrees C had more surface-adsorbed water and hydroxyl group to enhance the photocatalytic activity. X-ray diffraction spectra indicated that anatase phase was the predominant structure in N-doped TiO2.
