Paper Abstract

Tin alkoxides are precursors used as preparing thin films by the sol gel method. In this paper, the author has prepared tin alkoxides by the reaction involving alcoholic solutions of tin chloride with ammonia gas. The ordered mesoporous tin dioxides also have been synthesized by the alcoholic sol-gel method from the precursors. Using the dip coating method, thin films have been uniformly deposited on some substrates, such as glass, silica and so on. X-ray diffraction (XRD), differential thermal analysis (DTA) and infrared spectroscopy (IR) microscopy have been used to characterizing the mesostructures and morphology formed under the room temperature as well as calcinations at different temperature. The surface areas of material, evaluated from Brunauer Emmett Teller (BET) formula .indicated the surface areas about 296m2/g and 176m2/g for calcinations at 350°C and 400°C respectively. In addition, the gas-sensing properties of thin film sensor of the mesoporous SnO2 have been investigated. The results indicated the sensitivity of mesoporous SnO2 sensor was superior to that of a conventional non-porous SnO2.
