Purposes-To summarize the new progress of the chemically modified electrode of gra- phene in recent years and to provide some references for analytical researchers because graphene is car- bonaceous materials formed by monolayer two-dimensional hexagonal lattice structure and has been widely used in the field of electroanalytical chemistry due to its unique electronic structure as well as physical and chemical properties. Methods-By referring to relevant literature at home and abroad, the latest development of graphene chemical modification electrode are summarized briefly. Results-From two aspects of the modified electrode based on graphene and graphene composite, the research on gra- phene and its composite in the field of electrochemical analysis from 2014 to January 2017 is reviewed and analyzed, pointing out that the catalytic mechanism and synergistic effects of graphene composite should be further studied. Conclusions-A systematic and comprehensive reference is provided for peo- ple who research on the application of graphene in electrochemistry and its related research.
