Abstract
Au-functionalized SnO2 nanotubes were prepared for use as gas sensors using TeO2 nanowires as templates. Transmission electron microscopy revealed tube diameters, tube lengths and tube wall thicknesses ranging from 50 to 200 nm, 5 to 50 μm, and 13 to 18 nm, respectively. The Au-functionalized SnO2 nanotube sensors showed responses of 179?473 % to 1?5 ppm NO2 at 300 ?C. These values are much higher than those obtained using bare SnO2 nanotubes synthesized in this study and most other SnO2 one-dimensional nanostructure-based sensors reported in the literature. The NO2 gas sensing mechanism of the Au-functionalized SnO2 nanotube sensors is also discussed.
