以间苯二酚（R）和甲醛（F）为原料，在模板铁聚合物（IPC）存在下聚合，经碳化处理，制备了中空石墨多孔碳纳米球（CNS）材料。研究了碳化过程中快速加热对空心石墨碳纳米球形成的影响。通过透射电子显微镜（TEM）、X射线衍射（XRD）、拉曼光谱、体电导率测量和Brunauer-Emmett-Teller（BET）比表面积对快速加热得到的CNS的结构和性能进行了表征。与使用标准缓慢加热方法合成的CNS相比，在碳化过程期间在快速加热下观察到具有降低的附聚度的中空石墨CNS。关键词：碳纳米球，快速热解碳化，团聚
Hollow graphitic porous carbon nanosphere (CNS) materials are synthesized from polymerization of resorcinol (R) and formaldehyde (F) in the presence of templating iron polymeric complex (IPC), followed by carbonization treatment. The effect of rapid heating in the carbonization process is investigated for the formation of hollow graphitic carbon nanospheres. The resulting CNS from rapid heating was characterized for its structure and properties by transmission electron microscope (TEM), x-ray diffraction (XRD), Raman spectroscopy, bulk conductivity measurement and Brunauer-Emmett-Teller (BET) surface area. Hollow graphitic CNS with reduced degree of agglomeration is observed under rapid heating during the carbonization process when compared to the CNS synthesized using the standard slow heating approach. Key words: carbon nanosphere (CNS), rapid pyrolytic carbonization, agglomeration
