| 中文摘要 | SnO2 flat-type coplanar gas sensor arrays were fabricated by a screen-printing technique based on SnO2 nanopowders prepared by a sol-gel method. The SnO2 flat-type coplanar gas sensor arrays had good acetone gas-sensing characteristics such as a fast response, short recovery time, and an almost linear response to acetone concentration of 1-100 ppm. The response could reach 2.11 for acetone concentration as low as 1 ppm, and the response and recovery times for 1 ppm acetone were 8.9 and 10 s, respectively. The surface reactions were investigated by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) at different temperatures, and a possible sensing mechanism was proposed. Formate, acetate, carbonate ions, CH3O(ads), CO2, H2O, and adsorbed acetone were detected when the SnO, flims were exposed to 100 ppm acetone at different temperatures. |
