摘　　要：石墨烯因具有高的电子迁移率和超大的比表面积而有望成为新一代的气敏材料,近年来有关石墨烯气体传感器的研究工作逐年增加。概述了石墨烯的结构和特性;介绍了典型石墨烯气体传感器的工作原理;综述了本征和功能化石墨烯的多种气体气敏特性在理论和实验上的研究现状。Owing to its exceptionally high carrier mobilities and extremely large surface-to-volume ratio, gra- phene is thought to be a promising material for gas sensing. Recent years there are more and more reported articles about gas sensitivity of graphene. The structure and properties of graphene are summarized and the operational princi- ple of gas sensor based on graphene is also described. We mainly introduced the recent theoretical and experimental status on sensitivity of pristine and modified graphene to various gases.
