Multi-walled carbon nanotubes (MWCNTs) were successfully coated with tin-dioxide (SnO2) nanoparticles using both hydrothermal process and sol-gel technique under different solvent conditions. The obtained MWCNTs/SnO2 nanocomposites had the mass ratio of the components 1:4, 1:8 and 1:50, respectively. The as-prepared nanocomposites were characterized in detail using scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) technique. On the base of these materials gas-sensor structures are developed. The high sensitivity to methanol and ethanol vapour as...
