Soft Template Route for Synthesis of Super-microporous Carbons with Excellent Adsorption Property for Organic Dye

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600m2/g,且孔径分布在超微孔范围(1.2nm);对有机染料(罗丹明B)的最大吸附容量为120mg/g.

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.N2 isotherm shows that the sample has a large BET surface area （600 m^2/g） and obviously supermieropore （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.
