摘要
以2SnCl4·5H2O和SbCl3为原料，采用气-液界面法制备纳米ATO粉体，用粒度分析仪、X射线衍射仪、x射线光电子能谱仪及透射电子显微镜研究不同掺杂量下粉体组成、分布情况以及尺寸形貌；采用宽频介电阻抗谱仪测量不同掺杂比例样品的电性能，研究表明，采用气-液界面法制备的ATO纳米粉体粒径小、分布窄，掺杂剂分布均匀，表现出优异的电性能。当掺杂量为10At％时，所制备的粒径为10nm左右，表现出最佳的导电性能，电导率达到1．64×10-2S·cm-1。该制备方法对于其他复合纳米粉体的合成制备具有重大借鉴意义。
Sb-doped SnO2 （ATO） nano-composites were prepared by the gas-liquid interface precipitation method with SnCl4·5H2O and SbCl3, different doping amount of the powders＂ composition, distribution and size morphology were analyzed by the X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy. Effects of different doping ratios on powders＂ conductivity were investigated with broadband dielectric spectrometer. The results indicated that the Sb-doped SnO2 nano-powders prepared by gas-liquid interface was small particle size, narrow distribution, uni- form dopant distribution and showing excellent electrical properties, And Sb-doped SnO2 with 10At% doping contents had a particle size of lOnm could show the best conductive properties, conductivity reached 1.64×10-2S·cm-1, The gasliquid interface precipitation method has a significant reference to other composite powders preparation.
