Synthesis of TiO2 Nanocoral Structures in Ever-Changing Aqueous Reaction Systems

摘要: A far-from-equilibrium strategy is developed to synthesize coral-like nanostructures of TiO2 on a variety surfaces. nanocoral structures consist anatase base film and rutile nanowire layers, they are continuously formed substrates immersed in aqueous TiOSO4–H2O2. The sequential deposition starts with hydrolysis condensation reactions titanium peroxocomplexes the phase, resulting amorphous film. serves as adhesive interface which succeeding growth nanowires occur. This initial reaction accompanied by shift pH media, favorable condition for nanocrystals. During films transformed phase. These occur at temperatures low 80 °C, mild synthetic allows use wide range such ITO (indium tin oxide), glass, even orga...
