▎ 摘　　要

Graphene is a new 2D nanomaterial with outstanding material, physical, chemical, and electrochemical properties. In this review, we first discuss the methods of preparing graphene sheers and their chemistry. Following that, the fundamental reasons governing the electrochemistry of graphene are meaningfully described Graphene is all excellent. electrode material with the advantages of conductivity and electrochemistry of sp(2) carbon but without the disadvantages related to carbon nanotubes, Such as residual metallic impurities. We highlight important applications of graphene and graphene nanoplatelets For sensing, biosensing, and energy storage.
