| 摘 要： | 以表面活性剂F127为模板剂制备了有序中孔碳材料，研究了影响中孔碳孔径分布及有序性的各工艺参数，采用XRD, SEM, TEM和N2吸/脱附等手段对有序中孔碳进行了表征. 结果表明，F127用量、反应温度、搅拌时间、碳化温度和碳化升温速率等因素直接影响中孔碳结构的有序性及孔径分布. F127用量为40%、反应温度40℃、搅拌时间30 min、碳化温度800℃、升温速率1℃/min时，所得中孔碳有序性好且孔径分布比较集中.

| Abstract: | Ordered mesoporous carbon material was prepared by using surfactant agent F127(EO106PO70EO106) as template, and the effects of different process parameters on the pore size and orderliness of mesoporous carbon were studied.The material was characterized by XRD, SEM, TEM and nitrogen absorption/desorption.The results show that the amount of F127, reaction temperature, mixing time, carbonization temperature and heating rate have direct influences on the pore size and orderliness of mesoporous carbon.When the ... |
