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.

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2～7 nm。
