Graphitic carbon nitride based materials for electrochemical energy storage

Abstract

Graphitic carbon nitride (g-C₃N₄), with a unique structure analogous to graphite, has attracted ever-increasing attention for electrochemical energy storage due to its high surface area, metal-free characteristic, low cost and facile synthesis. Nevertheless, pristine g-C₃N₄ demonstrates poor electrical conductivity along with serious irreversible capacity loss. Therefore, different categories of g-C₃N₄-based materials with enhanced performance have been widely explored. This review mainly introduces g-C₃N₄-based materials for application in energy storage devices, including batteries and supercapacitors. The relationship between structures and electrochemical properties is elaborately discussed. Furthermore, historical development, future challenges and prospects in this field are also included.
