Template technique with carriers

Nanoporous carbon with narrow pore-size distribution can be prepared directly via a one-step nanocasting technique by carbonization of cyclodextrin-silica organic-inorganic hybrid composite.[260] The method consists of preparing a cyclodextrin-templated silica mesophase via soft chemistry, followed by direct carbonization of the occluded cyclodextrins. The nanocasting procedure provides granules (in millimeter scale) or monoliths (in centimeter scale). Cyclodextrins can be employed not only as structuredirecting templates but also as carriers for metal nanoparticle precursors.
