以花生壳为碳源,氯化锌为活化剂制备了花生壳基活性炭材料。采用扫描电子显微镜(SEM)、比表面积及孔径分析仪和电化学工作站分别对材料的结构和电化学性能进行了测试。结果表明,所制得材料具有丰富的孔隙结构。随着活化剂比例的增加,活化程度加深,微孔比例减小,外部孔比例增加,比表面积可达1821m2/g;材料具有良好的储电性能,比电容可达325F/g。

Peanut shells as a carbon source, zinc chloride as activator prepared peanut shell-based activated carbon material. The structure and electrochemical properties of the materials were tested by scanning electron microscopy (SEM), specific surface area and pore size analyzer and electrochemical workstation. The results show that the prepared material has a rich pore structure. With the increase of activator ratio, the degree of activation is deepened, the proportion of micropores is decreased and the proportion of external pores is increased, and the specific surface area is up to 1821 m2 / g. The material has good storage performance and the specific capacitance is up to 325 F / g.
