Description

General description

Our titanium(IV) oxide, anatase nanopowder is a fine white powder composed of titanium dioxide nanoparticles with a particle size less than 25 nm. Anatase is a metastable polymorph of TiO₂, which is less hard and less dense than the rutile polymorph. Optically, anatase nanopowder has a lower refractive index, absorbs less UV light, and exhibits greater photocatalytic activity than the rutile polymorph. Consequently, anatase is often preferred in applications where photocatalytic activity is desired, such as self-cleaning surfaces and solar cells.

Application

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.
