07-O-01 - Ordered mesoporous carbon molecular, sieves by templated synthesis: the structural varieties

This chapter discusses the template synthesis of ordered mesoporous carbon (OMC) molecular sieves. OMC of various structures, designated as CMK-1∼5, have been synthesized by the carbonization of sucrose, furfuryl alcohol, or other carbon sources inside silica or aluminosilicate mesopores that are interconnected into three-dimensional networks, such as in MCM-48, SBA-1, and SBA-15. The mesoporous carbon molecular sieves, obtained after template removal, show transmission electron microscopy (TEM) images and X-ray diffraction (XRD) patterns characteristic of the ordered arrangement of uniform mesopores. The OMC, which are opening up a new area of the nanoporous materials, exhibit high Brunauer–Emmett–Telle (BET) specific surface areas, excellent thermal stability in inert atmospheres, and strong resistance to attack by acids and bases.
