| Outline of Final Research Achievements |
In this project, I have attempted hydrothermal synthesis of titania polymorphs with controlled morphologies and development of methodology for the morphological control. On the morphological control using molecular control agents, the effect of functional groups in compounds used as the molecular control agent on the anisotropic growth of rutile-type titania along c-axis was clarified. On the other hand, it was succeeded on synthesis of rutile crystals exposing facets with high energy such as high-index ones under mild conditions. In addition, synthesis of high-index faceted or nanosized brookite-type titania, which was difficult to obtained as the single phase, was attained. These achievements produced novel knowledge for morphological control of crystals.
