摘要
以酚醛树脂低聚物为有机前驱体、正硅酸四乙酯(TEOS)为无机前驱体、嵌段共聚物F127为模板,采用蒸发诱导三组分共组装的方法合成了具有高比表面积的有序介孔碳材料。利用X射线衍射仪(XRD)、透射电子显微镜(TEM)、傅里叶变换红外光谱仪(FTIR)、拉曼光谱仪(Raman)、氮气吸附脱附仪对该材料的组成、结构及形貌等进行了表征。结果表明,制得的有序介孔碳材料具有高度有序的二维六方介观结构、平均孔径为6.5nm、比表面积和孔体积分别高达2281m2/g和1.92cm3/g。
Ordered mesoporous carbons with high specific surface areas were prepared by evaporation induced triconstituent co-assembly method,with phenolic resin oligomers as organic precursor,tetraethyl orthosilicate（TEOS） as inorganic precursor and segmented copolymer F127 as template.The composition,structure and morphology of the prepared samples were characterized by XRD,TEM,FTIR,Raman and N2 sorption techniques.The prepared ordered mesoporous carbons had highly ordered two dimension-hexagonal mesostructured with the average aperture of 6.5nm,and the specific surface area and pore volume reached up to 2281m2/g and 1.92cm3/g,respectively.
