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.
