摘　　要：以生物质为原料衍生和仿生合成成为当前材料设计领域的热门主题。本文对生活废弃物—柚子皮通过碳化和KOH活化两步热处理,得到具有高比表面积、大孔容且部分石墨化的介孔碳材料,并对其作为燃料废水脱色剂和锂离子电池负极材料两方面应用进行初步研究。发现在650℃下活化制得的衍生孔碳的吸附脱色性能最佳,室温下,2h后水中亚甲基蓝染料被100%吸附。孔碳材料也表现出较好的电化学循环稳定性和倍率性能。Bionic synthesis and derivative synthesis using biomass as raw material have become a hot subject in material design field. Herein,we synthesized a biomass-derived mesoporous carbon with high surface area,big pore volume and partial-graphitized structure using Pomelo peel as green carbon source by high temperature carbonization and KOH activation two-step technique. The application study as adsorbent agent for dyestuffs wastewater and anode for LIBs was also studied. The results show that the porous carbon material prepared in 650℃ has better absorbility than graphite and other porous carbon actived at other temperature. Methylene blue dye in aqoues was absorbed absolutely. Besides,the porous carbon also exhibits good electrochemical cycling stability and C-rating performance.
