Abstract
The pristine In2O3 nanotubes were synthesized by electrospinning and subsequent calcination. Scanning electron microscope, X-ray powder diffraction and transmission electron micrograph were employed to analyze the morphology and crystal structure of the as-synthesized nanotubes. Gas-sensing properties of the as-synthesized In2O3 nanotubes were investigated by exposing the corresponding sensors to toluene, acetone, ethanol, formaldehyde, ammonia and carbon monoxide at 340℃. The results show that the gas sensor possesses a good selectivity to toluene at 340℃. The response of the In2O3 nanotube gas sensor to 40 ppm is about 5.88. The response and recovery times are about 3 s and 17 s, respectively.-
