摘　　要：石墨烯因其出色的导电性能以及独特的物理和化学属性,在电化学传感器领域获得了广泛应用。虽然氧化石墨烯引入的含氧官能团会降低其导电性,但越来越多的研究表明,这些官能团在提高电催化活性、增强抗污染能力及促进功能化等方面发挥关键作用,这些特性对于电化学传感器的性能至关重要。本文全面综述了近年来基于含氧官能团的单层及多层石墨烯碳结构(统称为氧功能化石墨烯,GO)在电化学传感应用领域的进展。介绍了GO在电催化、抗污染、功能化等方面的基础性质,包括结构、表面官能团种类、导电性、亲疏水性、与生物分子的相互作用以及电化学窗口等;深入探讨了这些性质如何综合影响电催化活性、防污染和功能化的性能和机理;对基于GO的电化学传感器应用进行了分类讨论;展望了GO在电化学传感领域的未来发展。基于GO的电化学传感器在生物样品分析、活体检测和可穿戴设备方面将展现出巨大的应用潜力。Graphene,known for its excellent electrical conductivity and unique physical and chemical properties,has found widespread application in the field of electrochemical sensors.Although the introduction of oxygen-containing functional groups in graphene oxide reduces its conductivity,an increasing number of studies have shown that these functional groups play a crucial role in improving electrocatalytic activity,enhancing anti-pollution capabilities,and promoting functionalization,all of which are vital for the performance of electrochemical sensors.This article comprehensively reviews the progress in the application of single and multi-layered graphene carbon structures with oxygen-containing functional groups(collectively referred to as oxygen-functionalized graphene,GO)in electrochemical sensing in recent years.The paper first introduces the basic properties of GO related to electrocatalysis,anti-fouling,and functionalization,including structure,types of surface functional groups,conductivity,hydrophilicity and hydrophobicity,interaction with biomolecules,and the electrochemical window.It then delves into how these properties collectively affect the performance and mechanisms of electrocatalytic activity,anti-pollution,and functionalization.Following this,the article discusses the classification of applications for electrochemical sensors based on GO.Finally,it looks forward to the future development of GO in the electrochemical sensing field.Electrochemical sensors based on GO are expected to show significant potential in the analysis of biological samples,in vivo testing,and wearable devices.
