摘要：

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, N-2 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 562 m(2)/g, large pore volume of 0.57 cm(3)/g and narrow pore size distribution centered at 3. 57 nm. The structure of the OMC is stable at 300 degrees C in air, showing good thermal stability. Electrical conductivity measurements show that the OMC material has an average electrical resistance of 0. 16 Omega center dot cm.
