Preparation and Characterization of Nitrogen-Doped TiO₂ Decorated with Different Metal Ion

Abstract:

In this paper, nanotubular TiO₂ obtained by hydrothermal method was selected as precursor to prepare metal ion decorated TiO_2-xN_x via a facile and one-pot method. As-synthesized M/TiO_2-xN_x (M references to Pd, Fe, Ni, Li) photocatalysts were characterized by means of X-ray diffraction, diffuse reflectance spectrometry, fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The photocatalytic activities of different metal ion decorated TiO_2-xN_x samples were compared by monitoring the photocatalytic oxidation of propylene under both ultraviolet light (UV) and visible light (Vis) irradiation. It was found that Pd/TiO_2-xN_x sample possessed the highest photocatalytic activity under both UV and Vis irradiation. The better crystallinity, better visible light absorption, higher hydroxy concentration were contributed to the best photocatalytic performance of Pd/TiO_2-xN_x.
