The Effect of Different Concentration of Nitrogen in N, S Codoped TiO2
In this paper, the degradation of organophosphorus pesticide by nitrogen and sulfur codoped TiO2 photocatalysts under iodine-tungsten lamp irradiation has been investigated. And we adjusted the concentration of nitrogen to see the change of particle size of nitrogen and sulfur codoping TiO2. According to the X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), the different concentration of N, S codoping under different calcination temperature was discussed. N, S codoped TiO2 sample has a smaller particle size at a low anneal temperature than the one at high anneal temperature.
