Tin dioxide (SnO2) nanocrystalline were prepared by Sol–Gel method from SnCl2·2H2O. The obtained products have been annealed at different temperature (200, 400, 600 °C) and characterized by X-ray diffraction (XRD), atomic force microscope (AFM), scan electronic microscope (SEM) and FTIR spectroscopy measurements. The results indicate that the crystalline powder is tin dioxide (SnO2). The AFM show the particles size increase from 76.1 to 98.6 nm as the calcination temperature rises from 200 °C to 600 °C. The XRD analysis exhibits a rutile tetragonal phase of the SnO2 nanocrystals.
