Porous nitrogen-rich carbon materials from carbon self-repairing g-C₃N₄ assembled with graphene for high-performance supercapacitor

Abstract

Porous nitrogen-rich carbon derived from carbon self-repairing g-C₃N₄ with improved conductivity and more active sites exhibited high capacitance and good cycling performance due to the oxygen-containing groups and the carbon atoms close to the nitrogen as confirmed by XPS.
