摘要：
Flexural In2O3 nanowires with high aspect ratios were synthesized via a hydrothermal-annealing route. The as-synthesized In2O3 nanowires had diameters of 30-50 nm and length up to several microns. Various reaction parameters, such as the kind of reagents, the time of hydrothermal treatment, annealing time and annealing temperature, were investigated by a series of control experiments. The as-synthesized In2O3 nanowires showed excellent gas-sensing properties to NO2 in terms of sensor response and selectivity. (c) 2007 Elsevier B.V. All rights reserved.
