Graphitic carbon nitride nanomaterials for high‐performance supercapacitors

Abstract

Abstract Graphitic carbon nitride is a promising material as an electrode material for advanced electrochemical energy storage devices because of its controllable structure, physicochemical properties, and abundant active sites. However, its intrinsic properties as electrode materials can not be fully expressed owing to limited electrical properties, which impede charge transfer and material exchange inside devices. During the past decade, the challenge has been addressed through material engineering strategies, such as exfoliation and composition, and then advanced energy devices, such as supercapacitors, have been assembled. In this regard, a timely review of graphitic carbon nitride for high‐performance supercapacitors requires to be put forward for summarizing past studies and inspiring future research works as well. This review article summarizes recent progress in material synthesis and property regulation of graphitic carbon nitride nanomaterials and their application in assembling advanced supercapacitors with high energy density and superior working stability. Finally, based on existing research and our experimental experience, a perspective for directing future research has been presented concerning material synthesis and electrochemical application of graphitic carbon nitride.
