采用水热退火法制备了具有高长径比的弯曲In2O3纳米线。所合成的In2O3纳米线直径为30 - 50 nm，长度可达几微米。通过一系列的控制实验，研究了各种反应参数，如试剂种类、水热处理时间、退火时间和退火温度。所合成的In2O3纳米线在传感器响应和选择性方面对NO2表现出优异的气敏性能。
Flexural In2O3nanowires with high aspect ratios were synthesized via a hydrothermal–annealing route. The as-synthesized In2O3nanowires had diameters of 30–50nm 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 In2O3nanowires showed excellent gas-sensing properties to NO2in terms of sensor response and selectivity.
