Mesoporous perovskite titanates via hydrothermal conversion

We demonstrate the successful hydrothermal conversion of mesoporous TiO2 to mesoporous perovskite SrTiO3. This method allows for control of pore size distribution and can be readily applied for the preparation of other mesoporous titanates such as BaTiO3 and Li2TiO3. Such high-surface perovskites have potential in high-temperature applications due to their thermal stability.
