| Abstract
| - The structure of ordered mesoporous carbon materials CMK-5 was analyzed in detail bytransmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis by applyingthe recently developed continuous density function technique. The materials present two-dimensional (2-D) hexagonally ordered arrays of carbon nanopipes formed within themesopores of SBA-15 silica templates used for their fabrication. The series of CMK-5 carbonswere synthesized by applying the templates of different pore widths and two carbonprecursors: furfuryl alcohol and acenaphthene. All the materials were well-ordered,exhibiting five distinct XRD reflections, high nitrogen BET specific surface areas (about2500 m2/g), and large pore volumes (about 2 cm3/g). TEM analysis and XRD modeling allowedprecise determination of the mesostructure characteristics such as the nanopipe diameter,wall thickness, and shape. Around 15% of the space between the nanopipes was found to beoccupied by carbon interconnections formed inside the complementary pores of the SBA-15templates. The structure parameters determined correlated well with the synthesisprocedures and were fully consistent with the nitrogen adsorption and thermogravimetricdata. The differences in the properties and the formation mechanisms of the materialssynthesized by applying furfuryl alcohol and acenaphthene carbon precursors were analyzedbased on the whole scope of data obtained.
