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
