摘要
随着化石燃料的加速消耗和能源危机的日益加剧,作为新型储能元件的超级电容器引起了研究人员极大的关注。本文通过水热法制备了生物质衍生多孔碳,并对该材料的微观结构和元素组成进行分析,研究了其作为超级电容器电极材料的电化学性能。结果表明,经过掺氮处理的酸角衍生多孔碳材料其比电容从166 F·g-1提高到了232 F·g-1,说明掺杂能有效提高生物质衍生多孔碳材料的电容性能。
With the accelerated consumption of fossil fuels and the increasing energy crisis,supercapacitors,as new energy storage components,have attracted great attention from researchers.In this paper,biomass-based porous carbon was prepared by hydrothermal method,and the microstructure and elemental composition of the material were analyzed.The electrochemical properties of the electrode as a supercapacitor electrode material were studied.The results show that the specific capacity of the biomassbased tamarindus indica-derived porous carbon material increased from 166 F·g^-1 to 232 F·g-1,indicating that doping can effectively improve the capacitance performance of biomass-derived porous carbon materials.
