Abstract
Graphene oxide–tin oxide (GO–SnO2) nanocomposite has been successfully prepared by a facile method via a hydrothermal treatment of aqueous dispersion of graphene oxide in the presence of tin chloride. The combined characterizations including X-ray diffraction, Raman, transmission electron microscopy and Brunauer–Emmett–Teller technique N2 adsorption–desorption analyses indicate the successful formation of GO–SnO2 nanocomposite with average crystal size about 14 nm. The gas sensing performances to ethanol, acetone, toluene, formaldehyde were studied for the GO–SnO2 composition samples. The gas sensing results exhibit that GO doped can dramatically enhance the gas sensitivity to the test gases and increase the selectivity to ethanol.
