模板法制备沥青烯基有序中孔炭

Ordered mesoporous carbons (OMCs) were synthesized from asphaltene using a template carbonization method. The OMC material was studied by scanning and transmission electron microscopy, Xray diffraction, N2 adsorption and thermal gravimetric analysis. Results show that the asobtained OMC material with graphitic frameworkconfined ordered structure is a reverse replication of the template, which has a relatively high surface area of 562m2/g，large pore volume of 0.57 cm3/g and narrow pore size distribution centered at 3.57nm. The structure of the OMC is stable at 300℃ in air, showing good thermal stability. Electrical conductivity measurements show that the OMC material has an average electrical resistance of 0.16Ω•cm.
