Porous carbon spheres for supercapacitor electrodes employing beet molasses which was a new raw material instead of conventional carbonaceous materials as precursor were produced in different ways. Porous carbons were prepared at various condition variables. The morphology, physical structure and electrochemical properties of the materials were characterized by scanning electron microscopy(SEM), nitrogen physisorption and electrochemical method. The materials had surface area of 2547 m2/g and specific capacitance of 170. 5 F/g, which showed large surface area and well electrical double-layer capacitor. In a word, the problem of the use of molasses on a large scale in sugar industry may be solved. Moreover, a new way of producing porous carbons will be provided.%以工业制糖的副产物糖蜜为新型碳源,替代传统多孔碳生产原料,制备出性能优异的多孔碳球超级电容器电极材料；探索了制备方法,优化了反应条件.利用全功能表面吸附仪、扫描电子显微镜及电化学方法对材料的结构、形貌和电化学性能进行了表征.结果表明,制得的多孔碳球比表面积高达2547 m2/g,且展现出优异的双电层电容性(170.5 F/g).本研究可解决制糖企业对糖蜜无法大规模利用的问题,并为多孔碳的制备寻求新方法.
