Research progress on pore structure and regulation methods of biomass carbon materials

综述了比表面积、孔隙结构和孔径分布对生物质碳材料电化学性能的影响;并针对孔隙结构这一影响因素进行了进一步探究,主要阐述了蜂窝状、网络状、管状和片状孔隙结构的生物质碳材料在电化学储能方面的优势,以及不同形状的碳材料的调控方法;简单介绍了有序碳材料的可控构建及其在电化学方面的应用;分析了多级孔结构碳材料的特点(清晰的层次结构、三维的连通孔道)。最后展望了生物质碳材料通过孔隙调控提高电极材料电化学性能的发展趋势。

The effects of specific surface area,pore structure and pore size distribution on the electrochemical performance of biomass carbon materials were reviewed;and further investigation was carried out for the pore structure as an influencing factor,mainly describing the advantages of biomass carbon materials with honeycomb,network,tubular and lamellar pore structures in electrochemical energy storage and the regulation methods of carbon materials with different shapes.The controlled construction of ordered carbon materials and their application in electrochemistry were briefly introduced and the characteristics of carbon materials with multi-level pore structure(clear hierarchical structure,three-dimensional connected pore channels)were analyzed.Finally,the development trend of biomass carbon materials to improve the electrochemical performance of electrode materials through pore regulation was foreseen.
