▎ 摘　　要

Graphene, a recently discovered carbon nanomaterial with carbon atoms tightly packed into a two dimensional honeycomb lattice, possesses many novel and unique physical and chemical properties because of its unusual monolayer atomic structure. Graphene has received a great deal of attention in fundamental and applied research. This review presents the current status of graphene synthesis, functionalization, and applications in chemistry. Specifically, the use of graphene for the fabrication of chemically modified electrodes, the preparation of chemical power sources, catalyst and medicinal matrices, and in gas sensors are summarized. Finally, further applications based on graphene are briefly introduced.
