Solution-based Synthesis of Two-dimensional Materials for Electrochemical Capacitors

초록

Two-dimensional (2D) materials, especially graphene and MoS2 sheets, have gained much attention and shown great promisefor the application in supercapacitors. To widely use the 2D materials for supercapacitors, highly efficient, low cost, and environmentallyfriendly synthetic methods for the preparation of 2D materials should be developed. Here, we will review recentlydeveloped solution-based processes for preparing 2D materials for supercapacitors. Chemical exfoliation-reduction, chemicalintercalation, and liquid phase exfoliation methods will be introduced. Moreover, the electrochemical characteristics of grapheneand MoS2-based electrodes for supercapacitors are summarized. In addition to solution-based processes, other challengesand opportunities are discussed in terms of controlling nanosheet compositions, sizes, and thicknesses.
