Graphene oxide (GO),with abundant oxygen functional groups,is one of the most promising sen-sing elements for high-performance gas sensors in low concentration detection.We review the progress of gas sensors based on graphene oxide,and discuss the gas sensing property of graphene oxide on humidity,NO2 ,H2 and CH4 ga-ses.Besides,the influence of the type of oxygen functional groups on the selectivity of gas sensors based on graphene oxide are discussed,and the problems in the practical applications are summarized.This review provides a powerful tool to explore potential applications of graphene oxide in gas sensors in the future.%氧化石墨烯因表面含有丰富的含氧官能团而具有十分优异的气敏性能，可应用于低浓度（ppb级）环境下气体的检测。综述了现阶段氧化石墨烯在气体传感器中的研究进展，分析了氧化石墨烯对湿度、NO2、H2、CH4的敏感性能，重点探究了氧化石墨烯表面含氧官能团的类型对其选择性的影响规律，并总结了目前研究中存在的问题，为后续开展氧化石墨烯气体传感器的研究与应用提供借鉴。
