外文摘要：The use of heterojunctions is a promising solution to the problem of cross-sensitivity in gas sensors.In this work,a carbon monoxide sensor based on the CuO/TiO2 heterojunction was designed and fabricated.Due to the good adsorption properties of CuO materials to CO,and the heterojunction interface charge transfer,the CuO/TiO2 thin film sensor exhibits high sensitivity to CO at room temperature.The response is as high as 10.8-200 ppm CO,about 10 times its response to H2.Interference from H2 is greatly reduced by optimizing the structure of the CuO/TiO2 heterojunction.This reliable detection of carbon monoxide with excellent discrimination against H2 is of great significance for the development of CO gas sensors.
