Abstract: High surface area and uniform nano-sized TiO2 and ZrO2 were prepared readily by the infiltration of metal alkoxides into the nanoporous SiO2, SBA-15 and the following selective dissolution of SiO2. The obtained particles of TiO2 and ZrO2, 8.1 nm were nanocrystalline of which the structure were anatase and tetragonal, respectively. The surface area and pore volume of the nanocrystalline metal oxides can be increased to above 200 m2g-1 and 0.30 cm3g-1, respectively.
