Preparation and characterization of ordered mesoporous carbon by simple template method
At present,methods for preparing ordered mesoporous carbon are usually complicate and time-consuming,in order to simplify the preparation process and shorten the experimental procedure, a method is proposed for directly preparing ordered mesoporous carbon without additional solvent. Ordered mesoporous carbon frameworks with two-dimensional hexagonal structure have been synthesized without extra solvent,by using triblock copolymer F127 as template and homemade low molecular weight phenolic resin as carbon precursor. The interaction between phenolic resin and F127 was measured by infrared spectroscopy;the structures of ordered mesoporous carbons were characterized by X-ray diffraction,transmission electron microscopy and N2 adsorption/desorption measurements. The effects of temperature on PF resin synthesis and template content on pore structures of ordered mesoporous carbons were investigated. The results show that the micropore surface areas,the pore volutnes and the pore size of the mesoporous carbon are 490m2/g、0.41cm3/g and 4.15nm respectively, when phenolic resin was synthesized at 70℃ and the mass ratio of F127 to phenolic resin is 1∶1.
