Ordered mesoporous silica have attracted much attention due to their potential application as their large pore diameters, high surface area, selective sorbent and catalyst support. In addition, mesoporous silica was used as a template for the synthesis of nanostructured new materials. Metal oxides have optical, catalytic, electronic property and so on. However it has low surface area. In order to increase the surface area, mesoporous metal oxides have been synthesized. In this work, we have used mesoporous silica KIT-6 and MSU-H as a template for the various mesoporous metal oxides via nano-replication. Mesoporous metal oxides such as Fe2O3, MnO2, Mn2O3, Fe2O3-Mn2O3, etc were obtained by the impregnation with desired metal precursor solutions into the cubic mesoporous silica, crystallization to metal oxides at desired temperature and subsequent silica removal using 1~2M NaOH aqueous solution. The characterization of mesoporous metal oxides is performed by XRD, FESEM, HRTEM and N2 sorption.
