Abstract
In2O3 nanotubes were synthesized as gas sensors using TeO2 nanowires as a template. Scanning and transmission electron microscopy revealed the tubes to have diameters of a few hundred nanometers, wall thickness of 25 nm and lengths up to a few millimeters. Multiple networked Au-doped In2O3 nanotube sensors showed responses of 187?1219% to 50?250 ppm C2H5OH at 300 1C. These responses are far superior to those obtained by undoped In2O3 nanotubes and stronger than those obtained by pure In2O3 nanowires at 370 1C. In addition, the ethanol sensing mechanism of the Au-doped In2O3 nanotube sensors is discussed.
