A novel N-doped TiO2/Chitosan (CS) composited film, as a promising alternative material, was prepared, and could be more potential compared with tradition materials for treating wastewater. When this material, N-doped TiO2/CS film, was used for removing Methyl Orange (MO) under simulated solar light irradiation, about 99% of total MO removal was achieved due to the combination effect of photo-degradation and adsorption processes. N-doped TiO2/CS photo-catalyst was characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR) analysis. The results indicate that there exist the reactive groups NH2, OH on the N-doped TiO2 film, and their contents in the prepared photo-catalyst are responsible for the photo-degradation and adsorption effect, which was confirmed by FT-IR. Hence, it is possible that using N-doped TiO2/ CS film as a simple method for removal of the pollutants in wastewater.
