摘要
室温下石墨烯具有电子迁移率高、比表面积大、机械强度高、化学稳定性和热稳定性优异、导电性好等独特性能, 是当今最受关注的二维材料之一。与传统无机氧化物材料相比, 石墨烯气体传感器具有工作温度低、能耗小、恢复性高的优点。文章对两种石墨烯气体传感器的研究进展进行了综述。根据气体选择性不同, 将石墨烯气体传感器分为检测CO和CO2气体传感器。分别对其灵敏度、气体响应灵敏度和响应时间等特性进行分析对比。此研究对此类传感器的应用与推广具有一定的指导意义。
Abstract
Graphene has unique properties such as high electron mobility, large specific surface area, high mechanical strength, excellent chemical and thermal stability, and high electrical conductivity at room temperature. It is one of the most popular two-dimensional materials today. Compared with traditional inorganic oxide materials, graphene gas sensors have the advantages of low operating temperature, low energy consumption, and high recovery. The research progresses of two graphene gas sensors were summarized in this paper. Firstly, according to the different gas selectivity, graphene gas sensors were divided into CO and CO2 gas sensors. Then, the sensitivity, gas response sensitivity and response time were analyzed and compared, respectively, which had certain guiding significance for the practical application and promotion of this type of sensor.
