In situ polydopamine coating-directed synthesis of nitrogen-doped ordered nanoporous carbons with superior performance in supercapacitors

Abstract

A facile route to fabricate nitrogen-doped ordered nanoporous carbons (NONCs) was developed based on in situ polydopamine coating onto the pore surface of ordered nanoporous silica. The NONC exhibits very attractive capacitive properties, including unusually large capacitances up to 538 F g⁻¹, highly efficient electrochemically active surface area and good cycling stability.
