摘要
Nanocrystalline rutile titanium dioxide (TiO2) samples doped with various amounts of nitrogen (N) atoms were prepared using a hydrothermal synthesis route and a polycrystalline TiO2 precursor. The doped rutile nanocrystallites were analysed with transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV-Vis spectroscopy. The Kubelka-Munk band-gap calculation were used to examine the UV-Vis reflectance spectra. The measurements of the photocatalytic activity were performed utilizing FT-IR. A remarkable increase in the photocatalytic activity of the doped rutile nanocrystallites was detected, when applying the isopropanol degradation method with UV-Vis light irradiation.
