Abstract

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
