| 摘 要： | 以InCl3.4H2O为原料,用微波水解法制备In2O3纳米颗粒,并用TEM、XRD对合成材料的形貌和结构进行了表征。结果表明,所制的产品为球形In2O3,平均粒径为20 nm;用静态配气法测试了材料的气敏特性,与恒温水解制备的氧化铟材料的气敏特性基本一致。5.0 V加热电压下,对50×10–6酒精蒸气有较好的气敏性能,灵敏度为9.51,响应/恢复时间为6 s/6 s。

| Abstract: | In2O3 nanopowder was synthesized by microwave hydrolysis employed InCl3.4H2O as raw material.The structure and morphology of the samples were characterized by XRD and TEM.The results indicate that mean grain size of In2O3 nanoparticles are 20 nm and morphology displays spherical.Gas sensing properties were measured with stationary state gas distribution method.The sensor has satisfactory response to 50×10–6 alcohol: Resistance sensitivity is 9.51,and response/recovery time is 6 s/6 s.The results are accorded with that measured from the sample produced by constant temperature hydrolysis. |
