abstract Tin(IV) oxide - carbon nanotube nanocomposites were synthesized by the sol-gel method without and with ultrasonication, microwave radiation, and cavitation. The synthesized products were examined by means of transmission electron microscopy (TEM), X-ray diffraction, and differential thermal analysis methods. The TEM micrographs have shown that the tin (IV) oxide was deposited onto the oxidized surface of MWCNTs. The X-ray diffraction patterns have shown that the crystallite size of the SnO2 was within the 6.7÷11 nm range. The thermal analysis data indicate that the thermal stability of the SnO2 - MWCNТs composites increases versus the initial carbon nanotubes. The scheme of transformations in the tin(IV) oxide - carbon nanotube nanocomposite synthesis by the sol-gel method was proposed.
