摘要: 通过无机-有机杂化的方式,将葡萄糖插层到六水合氯化高铁层板间,采用一步碳化和酸刻蚀技术制备得到二维结构纳米碳材料。利用扫描电镜、透射电镜、热重分析仪、X 射线衍射、拉曼光谱等表征方法对样品的微观结构和组成进行了分析。以6 mol/L KOH 为电解液,采用三电极体系对所得的二维纳米碳材料进行电化学测试。结果表明,在0. 5 A/g 电流密度下,所制备的二维碳材料质量比电容可以到达236 F/g,当电流密度上升到10 A/g,比电容依然能维持在201 F/g,比电容保持率为85. 2 %,具有良好的倍率性能;同时该电极还具有优异的循环稳定性,经过1 000次充放电循环过程,比容量几乎无衰减。

Abstract: In this study,two dimensional nanostructured carbon materials were prepared through inorganic and organic hybrid method that glucose was intercalated into the laminates of iron(III) chloride hexahydrate. The obtained hybrid composite was then thermally carbonized and followed by acid etching. The microstructure and composition of the samples were characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),thermogravimetric analysis (TG),X- ray diffraction(XRD),Ramanspectra and other characterization methods. A three electrode system was used to evaluate the electrochemical properties of the two-dimensional carbon materials and 6 mol/L KOH was used as electrolyte. The results showed that at 0. 5 A/g current density,the mass specific capacitance of the prepared two-dimensional carbon material electrode was up to 236 F/g. When current density increased to 10 A/g,the specific capacitance could still be maintained at 201 F/g,and the specific capacitance retention rate was 85. 2%,this indicated a good rate performance. In addition,the electrode also exhibited excellent cycling stability,which still maintained the initial specific capacitance after 1 000 cycles at a current density of 10 A/g.
