Abstract

Undoped, Ag-doped TiO2 and N-doped TiO2 anatase nanocrystals were successfully prepared from titanium tetraisopropoxide by sol-gel method. The as-prepared TiO2 nanocrystals were structural and morphological characterized by X-ray diffraction, DRUV-VIS spectroscopy, FT-IR spectroscopy, SEM microscopy and EDX analysis. The presence of doping ions, Ag and N, was confirmed by EDX elemental analysis. Also, the results shows that the anatase TiO2 has a particle size in the nanometer range about 20-30nm, calculated by Scherrer’s relation and also confirmed by SEM images..
