A facile and rapid preparation of highly crumpled nitrogen-doped graphene-like nanosheets for high-performance supercapacitors

Highly crumpled nitrogen-doped graphene-like nanosheets (CN-GLSs) with a high specific surface area (1169 m 2 g −1 ) and large pore volume (2.58 cm 3 g −1 ) are prepared from a macroporous resin via simultaneous urea gasification expansion and CaCl 2 activation methods. The CN-GLSs are tested as ele...

Zusammenfassung:Highly crumpled nitrogen-doped graphene-like nanosheets (CN-GLSs) with a high specific surface area (1169 m 2 g −1 ) and large pore volume (2.58 cm 3 g −1 ) are prepared from a macroporous resin via simultaneous urea gasification expansion and CaCl 2 activation methods. The CN-GLSs are tested as electrodes for supercapacitors and present excellent electrochemical performance.
