The serial SnO2 samples are synthesized by sol–gel method with using isopropanol, isobutanol, butanol, and isoamyl alcohol of different concentrations. As revealed, with increasing chain length of the corresponding alcohols or the size of their molecules, the surface area of fabricated SnO2 powders is increasing. As determined by X-ray analysis, in all investigated alcohols, the rutile-type crystalline SnO2 is obtained. As follows from the PEM images of synthesized samples, there are the spherical or nearly spherical particles with an average size of 15–40 nm, which form agglomerates of about 80–120 nm. The mechanism of reactions, which occur during the synthesis of tin(IV) oxide from tin(II) chloride by sol–gel method, is suggested.
