Catalytic Oxidation of Alcohol on SnO2 Ultrafine Particle Thin Film

Abstract

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
