Abstract :
Fluorine-doped anatase TiO2 nanoparticles are prepared using a simple sol-gel method in an NH4F-H2O-C2H5OH mixed solution using the precursor TTIP. The prepared samples are characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and photocatalytic properties. The anatase phase TiO2 nanoparticles are identified by X-ray diffraction data. The X-ray photoelectron spectroscopy indicated that fluorine is doped effectively and most fluorine dopants might be present in the surface of TiO2 nanoparticles. The photocatalytic activity is evaluated by photocatalytic oxidation decomposition of methylene blue (MB) in atmospheric air under Visible light illumination. 84% photocatalytic efficiency observed for 5W% fluorine-doped TiO2 nanoparticles. The higher photocatalytic activity predicted is due to the formation of photocatalytic reactive 〖OH〗^(˙̇)radicals.
