摘要
This study reports a facile and green preparation of heteroatom-doped porous carbon nanosheets derived from deep eutectic solvents (DES). N-doped or N, S-co-doped carbon porous nanosheets are produced by varying the composition of glucose-based DES followed by a simple KOH activation, which show highly improved capacitances. Besides, micro-supercapacitors based on N-doped carbon nanosheets exhibit a specific capacitance of 23.2 mF cm−2 at 0.2 mA cm−2, which is among the best compared to the results reported in the literature. This study reports a facile and green preparation of heteroatom-doped porous carbon nanosheets derived from a deep eutectic solvent (DES). Typical N-doped porous nanosheets produced from glucose-based DES with high specific surface area and N-doping amount show a high capacitance of 298 F g−1. Besides, corresponding micro-supercapacitors exhibit a high specific capacitance of 23.2 mF cm−2.
