Abstract: In this article, the porous columned SnO2 ultrafine particle thin films are prepared on silicon by PCVDtechnique. The variations of XPS, IRand film electrical resistance are researched during the gas adsorption, desorption and oxidation process on the film surface. After the analysis of alcohol the oxidation mechanism induced by the adsorbed O- and O2- on the film surface is proposed. The results of gas-sensitive properties of SnO2 ultrafine particle film are explained satisfactorily.

Key words: SnO2 film, Alcohol, Catalytic oxidation, Gas-sensitive property
