摘要：
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 CaCl2 activation methods. The CN-GLSs are tested as electrodes for supercapacitors and present excellent electrochemical performance.
