主　　题：carbon monoxide cross-sensitivity gas sensor heterojunction hydrogen 

摘      要：The use of heterojunctions is a promising solution to the problem of cross-sensitivity in gas *** this work,a carbon monoxide sensor based on the CuO/TiO_(2)heterojunction was designed and *** to the good adsorption properties of CuO materials to CO,and the heterojunction interface charge transfer,the CuO/TiO_(2)thin film sensor exhibits high sensitivity to CO at room *** response is as high as 10.8–200 ppm CO,about 10 times its response to H_(2).Interference from H_(2)is greatly reduced by optimizing the structure of the CuO/TiO_(2)*** reliable detection of carbon monoxide with excellent discrimination against H_(2)is of great significance for the development of CO gas sensors.
