摘要:
以二水合二氯亚锡为原料，无任何添加剂，通过微波水热法快速合成氧化锡（SnO2）纳米棒．使用X射线衍射和扫描电子显微镜对样品的结构、形貌进行表征．研究发现，制备的SnO2纳米棒颗粒尺寸均一，分散性较好，纳米棒的表面布满颗粒状的突起．以制得的SnO2纳米棒构筑旁热式气敏元件，采用静态配气法测试了气敏元件对乙醇、甲醇、丙酮和氨气等气体的敏感性能．结果表明，该气敏元件对乙醇具有灵敏度高、检测下限低、选择性好、响应和恢复迅速等优点．
Abstract:
Tin dioxide nanorods were successfully synthesized by a microwave-assisted hydrothermal method with Tin(II) chloride dehydrate as the raw material without any additives. The structure and morphology of the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The result indicates that the particle size of the SnO2 nanorod is uniform and relatively dispersive. It is found that the surface of nanorods is filled with irregular protuberances. The sensibilities of such a SnO2 sensor to ethanol, methanol, acetone, ammonia, and so on were measured by the static volumetric method. The sensor exhibits high sensitivity, low detection limit, excellent selectivity, fast response and recovery characteristics to ethanol.
