【摘要】：本论文针对纳米多孔炭材料具有比表面积高,总孔容大、孔结构可调、导热性高、机械稳定性强和易于批量生产等特点和优势,开展炭材料的可控合成及其在超级电容器中的应用研究。重点采用不同的碳源和模板剂,通过模板炭化法制备了系列的纳米多孔炭材料,采用XRD、FESEM、HRTEM、Raman、XPS、BET等技术手段对炭材料的结构进行表征,并采用三电极体系(或二电极体系)对超电容性能(如CV曲线、充放电曲线、Ragone图、Nyquist图、循环稳定性等)进行测定。论文的主要研究内容如下：1.利用邻苯二甲酸氢钾为炭源,商品的Mg、Zn、Al粉体为硬模板,来合成纳米多孔炭材料。2.通过直接在800℃炭化柠檬黄和Ca(OAc)2·H2O混合物,合成了具有高BET比表面积和大孔容的氮掺杂多孔炭材料。采用水杨酸锌配合物为前驱体、Mg(OAc)2-4H2O为模板剂,合成了高性能的纳米多孔炭材料。使用1,10-菲罗啉(或苯并咪唑)为炭/氮源,柠檬酸镁为模板,合成含氮掺杂的纳米多孔炭材料。3.直接碳化对苯二甲酸锌和邻苯二甲酸氢钾,合成了用超级电容器的高性能的纳米多孔炭材料。4.以离子交换树脂为炭源,通过模板碳化-KOH活化法合成多孔炭材料,并在EDLC领域具有良好的应用。以ZnCl2为普适的活化剂,利用镁试剂、茜素黄和柠檬黄为炭源/氮源,通过模板炭化-活化法合成氮掺杂多孔炭材料。
[Abstract]:In this paper, nano-porous carbon materials have the advantages of high specific surface area, large total pore volume, adjustable pore structure, high thermal conductivity, strong mechanical stability and easy mass production. The controllable synthesis of carbon materials and its application in supercapacitors were studied. A series of nano-porous carbon materials were prepared by template carbonization with different carbon sources and templating agents. The structure of the carbon materials was characterized by means of XRDD-FESEMN HRTEMN Raman-XPS-BET and so on. The performance of supercapacitor (such as CV curve, charge / discharge curve, Nyquist diagram, cycle stability, etc.) was measured by three-electrode system (or two-electrode system). The main contents of this thesis are as follows: 1. Nano-porous carbon material .2was synthesized by using potassium phthalate as carbon source and commercial MgOZnZn-Al powder as hard template. Nitrogen-doped porous carbon materials with high BET specific surface area and large pore volume were synthesized by direct carbonization of lemon yellow and Ca (OAc) _ 2H _ 2O at 800 鈩，
