Mesoporous perovskite titanates via hydrothermal conversion

Abstract

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.
