摘要/Abstract

摘要： 以聚苯乙烯微球以及F127嵌段共聚物自组装结构为模板, 酚醛树脂低聚物为碳前驱体, 双模板法合成了大孔-介孔分级孔结构的炭材料. 对样品进行了X射线衍射(XRD)、扫描电镜(SEM) 、透射电镜(TEM) 和氮吸附-脱附测试, 并研究了样品的电化学性能. 结果表明, 利用这种简便的合成方法可以得到具有三维连通大孔以及二维有序介孔结构的分级孔结构炭材料, 大孔尺寸在 1μm左右 , 介孔孔径集中分布在5nm, 比表面积为 353.8m²/g , 孔容0.36cm³/g. 利用三电极体系测试了产品作为电化学双电层电容器电极材料的性能, 在50mA/g的电流密度下, 放电质量比电容为40F/g .

Abstract: Hierarchical macro-mesoporous carbon material (HMMC)was synthesized successfully <>via a facile dual-templating method usingresols as carbon source, in which polystyrene (PS) colloid was selected as macroporoustemplate and Pluronic F127 as mesoporous template. After thermosettingtreatment and carbonization step, HMMC can be obtained. The product was characterizedby XRD, SEM, TEM and N₂ adsorption techniques. The electrochemical performanceof HMMC was evaluated by cyclic voltammetry and galvanostatic charge/dischargemethods using an electrochemical workstation and a battery testing system. Resultsshow that HMMC material has three-dimensional connected macroporous structurewith pore size of 1μm andordered mesoporous windows with average pore size of approximately 5nm. BET surface area of the product is 353.8 m²/gand pore volume is 0.36cm³/g. TheCV curves of HMMC are quasi-rectangular, the specific capacitance of product iscalculated to be about 40F/g at a constant current density of 50mA/g. It isanticipated that these novel materials synthesized by the simple methods havepotential applications in electrode materials.
