Aqueous solution processes are environmentally friendly and produce materials with excellent properties. We focus on the synthesis of crystals with controlled nano- and microstructures and the development of new materials using aqueous solution-based methods. Using water-soluble titanium complexes, various additives can be used to control morphology. As a result, titania polymorphs including not only anatase and rutile, but also brookite and TiO2(B) with various morphologies were synthesized. In addition, this approach produced magnetite, exposing high index facets. These crystals with controlled structures showed excellent properties. Moreover, the development of new complexes below 373 K was achieved using aqueous solution methods. Water plays a key role in the controlled synthesis of crystalline structures and morphologies and the development of new materials.
