摘要：
Nitrogen-doped TiO2 (N-TiO2) were prepared by the impregnation method using urea as a nitrogen source and TiO2-P25 as precursor. N-TiO2 was characterized by x-ray diffraction (XRD), UV-vis diffusion reflectance spectra (UV-vis DRS), Fourier transform infrared spectroscopy (FTIR), and x-ray photoelectron spectroscopy (XPS) techniques. XPS analysis indicates the incorporation of nitrogen in TiO2 lattice as O-Ti-N linkage. DRS spectra reveal the extended absorption to the visible range. Photocatalytic performance of the N-TiO2 was studied by testing the degradation rate of aqueous styrene under visible light. Also, the degradation kinetics of aqueous styrene and possibility of cyclic usage of N-TiO2 were investigated.
