摘要:
采用牺牲模板法经高温热解制备了氮修饰的石墨烯。BET分析结果显示,氮修饰石墨烯具有大的比表面积和明显的介孔特征。Raman光谱分析揭示,热解制备的氮修饰石墨烯具有高的石墨化程度。电化学研究结果显示氮修饰石墨烯具有高的超级电容性能,在0.5〖KG3x〗A·g.-1.的电流密度下的比电容达到190〖KG3x〗F·g.-1.。经1 000圈充放电循环后,氮修饰石墨烯的比容量还能保持原来的88%。
Abstract:
Nitrogen-modified graphenes (NGs) were prepared via high temperature pyrolysis by sacrificial template method. The BET analysis indicates that NGs possess a large specific surface area and significant mesoporous characteristics. Raman results reveal that NGs have a high degree of graphitization. The electrochemical results show that NGs present a high supercapacitor performance. The specific capacitance can reach 190〖KG3x〗F·g-1 at a current density of 05〖KG3x〗A·g-1, and the retention ratio of specific capacitance for NGs can maintain 88% after 1 000 galvanostatic charge-discharge cycles at 0.5〖KG3x〗A·g-1.
