目前制备有序介孔碳的方法工艺复杂、繁琐耗时，为了简化其制备工艺，缩短实验流程，本文提出一种不需要添加额外溶剂直接制备有序介孔碳的方法。以三嵌段共聚物F127为模板剂，自制低分子量酚醛树脂为碳前体，制备了具有二维六方结构的介孔碳。采用红外光谱对酚醛树脂和F127进行表征，研究了两者之间的作用力；采用X射线衍射、透射电镜和N2吸附/脱附等手段对介孔碳结构进行表征，研究了酚醛树脂的合成温度和模板剂用量对介孔碳结构的影响。结果表明酚醛树脂合成温度为70℃，F127：PF=1时，得到的介孔碳比表面积、孔容和孔径分别为490m2/g、0.41cm3/g和4.15nm。

At present,methods for preparing ordered mesoporous carbon are usually complicate and time-consuming,in order to simplify the preparation process and shorten the experimental procedure, a method is proposed for directly preparing ordered mesoporous carbon without additional solvent. Ordered mesoporous carbon frameworks with two-dimensional hexagonal structure have been synthesized without extra solvent,by using triblock copolymer F127 as template and homemade low molecular weight phenolic resin as carbon precursor. The interaction between phenolic resin and F127 was measured by infrared spectroscopy;the structures of ordered mesoporous carbons were characterized by X-ray diffraction,transmission electron microscopy and N2 adsorption/desorption measurements. The effects of temperature on PF resin synthesis and template content on pore structures of ordered mesoporous carbons were investigated. The results show that the micropore surface areas,the pore volutnes and the pore size of the mesoporous carbon are 490m2/g、0.41cm3/g and 4.15nm respectively, when phenolic resin was synthesized at 70℃ and the mass ratio of F127 to phenolic resin is 1∶1.
