摘　　要：石墨烯是一种新型二维碳材料,其比表面积大、导电性好、催化活性高、吸附能力强,是构筑高性能电化学传感器的理想材料。相对于石墨烯常用的氧化还原制备方法而言,液相剥离法具有过程简单、可控性强、高效环保以及对石墨烯结构破坏小等特点,在电化学传感领域备受关注。基于本课题组及国内外学者近年来的相关工作,本文重点综述了三种液相剥离石墨烯制备方法的原理,包括超声剥离、液相球磨剥离和电化学剥离,以及他们在电化学传感中的应用进展,并对未来研究进行了展望。Graphene is a new type of two-dimensional carbon material,with the advantages of large specific surface area,good electrical conductivity,high catalytic activity and strong adsorption capacity.It has been widely used in the field of electrochemical sensing,but the employed-graphene materials are mainly graphene oxides(GO)or reduced graphene oxides(rGO).The preparation of graphene by liquid-phase exfoliation has the advantages of simple operation,high efficiency,environmental protection,strong controllability and little damage to the graphene structure.Based on the related work of our research group in recent years,this paper summarizes the electrochemical sensing application of liquid-phase ultrasonically-exfoliated graphene,liquid-phase ball-mill-exfoliated graphene and electrochemically-exfoliated graphene.Moreover,the prospect of exfoliated-graphene in electrochemical sensing is also discussed.
