Template synthesis and characterization of ordered mesoporous carbons from asphaltene

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.
