Stability of mixed-oxide titanosilicates: dependency on size and composition from nanocluster to bulk

Nanostructured titanosilicate materials based upon interfacing nano-TiO 2 with nano-SiO 2 have drawn much attention due to their huge potential for applications in a diverse range of important fields including gas sensing, (photo)catalysis, solar cells, photonics/optical components, tailored multi-(...

Description
Summary:Nanostructured titanosilicate materials based upon interfacing nano-TiO 2 with nano-SiO 2 have drawn much attention due to their huge potential for applications in a diverse range of important fields including gas sensing, (photo)catalysis, solar cells, photonics/optical components, tailored multi-(bio)functional supports and self-cleaning coatings. In each case it is the specific mixed combination of the two SiO 2 and TiO 2 nanophases that determines the unique properties of the final nanomaterial. In the bulk, stoichiometric mixing of TiO 2 with SiO 2 is limited by formation of segregated TiO 2 nanoparticles or metastable glassy phases and more controlled disperse crystalline mixings only occur at small fractions of TiO 2 (
