摘要： 本文研究了由阴离子表面活性剂组成的微乳液在纳米SnO2气敏材料合成中的应用，研究了阴离子表面活性剂类型及肋表面活性剂对纳米SnO2材料平均晶粒度的影响．实验结果表明：由AES或K12和丁醇组成的微乳液可得到平均颗粒尺寸＜20nm，平均晶粒度只有6nm左右的均分散SnO2，用这种材料制成的气敏元件无需掺杂即具有较高的气体灵敏度．

Abstract: The application of microemulsion made of anion surfactants in preparing SnO2 naosized materials was studied, and the influence of different anion surfactants and assistant
surfactants on the mean grain size of nanosized SnO2 was also researched by XRD and TEM. It can be known from the experimental results, monodispersed SnO2 nanosized materials with the
mean grain size of about 6nm and average partical size smaller than 20nm can be obtained from the microemulsion composed of AES or K12 anion surfactant and butanol assistant surfactant, and it
has high sensitivity without catalysts and additives.

Key words: tin oxides, microemulsion, nanosized materials, gas, sensor, surfactant
