General description

Titanium (IV) oxide nanopowder is widely used in skin products, additives, and foods. Nano titania has been proved to be the most active photocatalytic semiconductor under ultraviolet radiation. Titanium isopropoxide, titanium (IV) butoxide has been used as precursor materials to synthesize nano-titania.


Titania paste may be used as a transparent coating for self cleaning glass.Low optical scattering titania-acrylate nanocomposites have been reported. Metal contacts in solar cells based on titanium dioxide and di-(isothiocyanate)-bis-(2,2′-bipyridyl-4,4′-dicarboxylate)ruthenium(II) have been studied.
