Abstract Due to the characteristics of thin thickness, rich active sites and short diffusion distance, the carbon nanosheets have been widely used as electrodes for energy storage in supercapacitors. Herein, N-doped mesoporous carbon nanosheets (N-MCS) were prepared by using cheap mica powder as template and resorcinol-formaldehyde (RF) resin as carbon precursor. The ethyl orthosilicate (TEOS) was introduces as porogen to create rich mesopores and to increase surface area. The ethylenediamine can be used not only as catalyst for TEOS hydrolysis and RF resin polymerization, but also as nitrogen dopant. The N-MCS faithfully replicated the template morphology, exhibiting sheet-like morphology, porous and N-doping characteristics, which can effectively improve the electrochemical performance.

用于高性能超级电容器的 N 掺杂介孔碳纳米片

摘要 由于碳纳米片具有厚度薄、活性位点丰富、扩散距离短等特点，被广泛用作超级电容器储能电极。在此，以廉价的云母粉为模板，间苯二酚-甲醛（RF）树脂为碳前驱体，制备了 N 掺杂的介孔碳纳米片（N-MCS）。引入原硅酸乙酯 (TEOS) 作为致孔剂以产生丰富的介孔并增加表面积。乙二胺不仅可以用作TEOS水解和RF树脂聚合的催化剂，还可以用作氮掺杂剂。N-MCS忠实地复制了模板形貌，表现出片状形貌、多孔性和N掺杂特性，可有效提高电化学性能。
