Blue Titania: The Outcome of Defects, Crystalline-Disordered Core-Shell Structure, and Hydrophilicity Change.

ABSTRACT: In this research, changes in several characteristics of partially reduced titania were studied. The reduction process used made it possible to gradually observe changes in the material depending on the amount of reducing agent used. We used NaBH₄ to impregnate commercial TiO₂ with isopropyl alcohol. Impregnated TiO₂ nanoparticles were dried and thermally treated in a nitrogen flow to obtain blue titania samples. Thorough spectroscopic characterization showed that oxygen atoms from hydroxyl groups, as well as from the surface, and the lattice of TiO₂ was consumed. This caused changes in the surface and even in the bulk of TiO₂ when the amount of reducing agent used was increased. Structural, optical, superficial, and textural characteri
