摘要:

以小分子炭氟表面活性剂[FSOCF3CF2CF2CF2CF2-(CH2CH2O)10](FSO)为超微孔模板剂, 通过酚醛预聚物和FSO间的氢键自组装作用实现其分子间的自组装, 经过水热处理和高温炭化合成超微孔炭材料, 并对其进行X射线衍射(XRD)测试、 氮气吸附测试和液相吸附性能测试. 结果表明: 该超微孔炭材料的孔结构有一定的规则性; 比表面积为600 m2/g, 且孔径分布在超微孔范围(1.2 nm); 对有机染料(罗丹明B)的最大吸附容量为120 mg/g.

Abstract:

Supermicroporous carbon with stable network has been successfully synthesized by the self assembly of carbonfluorine surfactant [FSOCF3CF2CF2CF2CF2-(CH2CH2O)10](FSO) with resol under high temperature hydrothermal conditions. After the carbonization of the sample at a high tempreture, which results in the shrinkage of the network, the small mesopore size carbon in the range of supermicroporous was obtained. XRD patterns show that the sample exhibits a certain order. N2 isotherm shows that the sample has a large BET surface area (600 m2/g) and obviously supermicropore (1.2 nm). Adsorption test shows that the resulted sample shows much better adsorption properties and a good recyclability, and the maximal adsorption capacity of organic dye RhB is 120 mg/g.

Key words: supermicroporous materials, hydrothermal synthesis, carbon based material, adsorption, selfassembly
