摘要：

WO3 nanotubes were synthesized using TeO2 nanowire templates. Transmission electron microscopy revealed the nanotubes to have tube diameters, lengths, and wall thicknesses ranging from 100-200 nm, 3-4 mu m, and 20-30 nm, respectively. The multiple networked WO3 nanotube sensors showed responses of 144-677% in the NO2 concentration range of 1-5 ppm at 300 degrees C. These responses were approximately double those observed for the WO3 nanorod sensors over the same NO2 concentration range. A model describing the gas sensing mechanism of WO3 NTs is also proposed.
