Marked Enhancement of Photocatalytic Activity of P-Doped TiO2 with Hydrothermal Method

Article Preview

Abstract:

Phosphor-doped titania nanoparticles were synthesized by a one step hydrothermal method. These samples which prepared by hydrothermal method exist in anatase phase has much higher photocatalytic activity for methylene blue (MB) degradation. In addition, MB degradation performance of the hydrothermal ones is also superior to that of the commercial P25. The resulting materials were characterized by X-ray diffraction (XRD), nitrogen physical adsorption at 77 K, X-ray photoelectron spectroscopy (XPS), etc. It can conclude the hydrothermal method proves to be more suitable to improve the photocatalytic performance.
