摘　　要：本研究使用果糖作为碳源,木质素磺酸盐协同三嵌段共聚物P123作为模板剂,经过水热碳化法和高温碳化法制备果糖基碳微球材料。探究了木质素磺酸盐对果糖在水热条件下的组装过程及调控机制,并分析果糖基碳微球材料在电化学领域的应用。结果表明,木质素磺酸盐的加入是微球表面形成波纹状突起的决定因素。经高温碳化处理过后得到中空多孔的Yolk-Shell果糖基碳微球材料具有良好的电化学性能,其比表面积为535. 04 m^2/g,孔容为0. 26 cm^3/g;在电流密度为0. 1 A/g时,其比电容为96 F/g,能量密度为3. 16 Wh/kg,功率密度为28. 06 W/kg。In this thesis,fructose-based carbon microspheres were prepared by hydrothermal carbonation and high temperature carbonationusing fructose as carbon source,lignosulfonate and P123 as the synergistic templates,the assembly process and regulation mechanism offructose under hydrothermal conditions were also studied. The results showed that the addition of lignosulfonate was a decisive factor for theformation of ripple protuberances on the surface of microspheres. The hollow and porous Yolk-Shell fructose-based carbon microspheres afterhigh temperature carbonization possessed superior specific surface area of 535. 04 m^2/g and a pore volume of 0. 26 cm^3/g. In addition,theyalso exhibited good electrochemical properties,the specific capacitance was 96 F/g,energy density was 3. 16 Wh/kg and power density was28. 06 W/kg when the current density was 0. 1 A/g.
