摘要
Ordered, mesoporous cobalt oxide was synthesized via a nanocasting pathway from organically modified large-pore Ia3d silica. A replica structure could be obtained,,which shows weak magnetic ordering at low temperatures due to the small size of the individual Co(3)O(4) domains forming the mesostructure.
