Abstract
Various kinds of mesoporous metal oxides with high thermal stabilities as well as crystalline frameworks have been successfully prepared using a mesoporous carbon as a template via nano-replication technique. This noble synthesis strategy for the preparation of mesoporous materials was carried out by the impregnation with the desired metal precursor. The mesoporous metal oxides calcined at 823 K exhibited 100–400 m 2/g of BET surface areas and 3–12 nm of pore sizes. The frameworks of the mesoporous metal oxide materials were crystallized by heat treatment at 1073 K in N 2 flow before the template removal. The results indicate that the mesoporous metal oxides can be obtained by the faithful negative replication of the structure of the mesoporous carbon.
