Fabrication and Hydrogen Sensing Property of In2O3 Nanotowers

Article Preview

Abstract:

In2O3 nanotowers have been fabricated on Au item-shaped parallel electrodes using thermal evaporation of the mixed powders of In2O3 and graphite with Au catalysts. The morphology and structure of the prepared nanorods are determined on the basis of field-emission scanning electron microscopy (FESEM) and x-ray diffraction (XRD). The self-assembly grown sensors of In2O3 nanotowers have excellent performance in sensor response to hydrogen concentration of 1000 ppm under operated temperature of 300°C.
