| 摘 要： | 以正硅酸乙酯(TEOS)为模板硅源,蔗糖为碳前体,添加N,N-二甲基甲酰胺(DMF)作为控制干燥化学助剂(DCCA),运用溶胶凝胶(Sol-Gel)法制备多孔炭材料。通过SEM和低温N2等温吸脱附等手段对材料的结构进行了测试与表征,结果表明:在优选工艺条件后,成功地制得了无龟裂混合干凝胶,溶硅去模后多孔炭材料孔径主要集中分布在2～7nm。

| Abstract: | Porous carbons were prepared by using a sol-gel method with tetraethyl orthosilicate (TEOS) as the silica template and sucrose as carbon precursor and adding N,N- dimethyl formamide(DMF) as drying control chemical additive(DCCA). SEM and N2 adsorption isotherms were used to test and characterize the pore structure of the as-prepared porous carbons. The results showed that DMF addition helped to make crack-free and fracture-free gel and the pore size distribution of resultant carbons ranged from 2 nm to 7 nm. |
