Discussion the Influence of Nonmetal Doped TiO₂

Abstract:

With the development of the science and technology, environmental pollution becomes one of the most serious problems all over the world. TiO₂ has gained intense research in the past decades due to its applications in environmental purification and solar energy conversion. In this paper, we discuss the influence of nonmetal (N, P, S) doped TiO₂ were prepared by hydrothermal method, the samples are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity of them was evaluated for the degradation of methylene blue under xenon lamp which has similar spectra to solar light. The results domenstrated that the N, P-codoped TiO₂ powders exhibited a better photocatalytic activity, and the optimum molar ratio is also investigated.
