采用SEM、FTIR和拉曼光谱、循环伏安（CV）、恒流充放电和电化学阻抗谱（EIS）等测试手段，比较系统地研究了不同石墨烯对超级电容器电化学性能的影响。结果显示：1）在相同的电压扫描速率下，氮掺杂石墨烯（N-G）电极的比电容最高，在1A/g下，N-G电极的比电容达到243.5F/g，而常规氧化石墨（GO）和还原氧化石墨烯（rGO）的比电容分别为43.5F/g和67.9F/g; 3）N-G具有最好的超级电容性能和优越的上级电化学性能，是一种理想的超级电容器电极材料。(C)2015中国材料研究会。由爱思唯尔公司制作和主持
The influence of variant graphenes on electrochemical performance for supercapacitors was studied comparatively and systematically by using SEM, FTIR and Raman spectroscopy, cyclic voltammetry (CV), galvanostatic charge/discharge and electrochemical impedance spectroscopy (EIS). The results revealed that: 1) the nitrogen-doped graphene (N-G) electrode exhibited the highest specific capacitance at the same voltage scan rate; 2) the specific capacitance of the N-G reached up to 243.5 F/g at 1 A/g, while regular graphite oxide (GO) was 43.5 F/g and reduced graphene oxide (rGO) was 67.9 F/g; 3) N-G exhibited the best supercapacitance performance and the superior electrochemical properties, which made it an ideal electrode material for supercapacitors.
