Graphitic Carbon Nitride (g-C3N4): A Proficient Electrode Material for Flexible Supercapacitors

Abstract

In the recent years, graphitic carbon nitride (g-C3N4), the metal-independent semiconductor, has captured immense interest in the field of supercapacitor technology owing to its numerous superior qualities together with layered morphology, unique physico-chemical features, ease of synthesis, low fabrication cost, environmental compatibility in addition to mechanical tenacity. Its’ graphitic type double-bonded nitrogen-rich layered structure promotes large number of reactive regimes and effective binding sites that considerably boost the electrochemical activity compared to other widely known graphene analogues. Besides, the architectural distinctiveness in g-C3N4 has introduced better designing opportunities for fabricating various types of nanocomposites with improved structural, electronic and electrochemical features. Thus, meticulously engineered g-C3N4 electrode materials have displayed high electrochemical and mechanical tenacity, which have opened up new dimensions in the manufacturing of flexible supercapacitors with advanced technological applications. This review addresses these recent progresses of g-C3N4 based systems in the electrochemical energy storage arena, embracing the current challenges faced and some of the prospects that are presumed to possibly emerge in the near future with this highly promising material.
