Preparation of Heteroatom Doped Graphene and Its Application as Electrode Materials for Supercapacitors

Owing to its vast surface area and remarkable electrical conductivity, graphene has attracted extensive attention in the realm of electrochemical energy storage. Nevertheless, its volumetric energy density as an electrode material is quite low, thus presenting certain difficulties in its application as an electrode material. Heteroatom doping is a viable approach to enhance the electrochemical properties of graphene, thereby augmenting the energy storage capability of graphene as an electrode material. This paper provides a summary of the preparation of heteroatom-doped graphene, examines how heteroatom doping affects graphene ' s electrochemical properties, explores the application of graphene in supercapacitors, and finally looks ahead to the future development course of this research domain.
