Titania
Titanium dioxide, also known as titania is the naturally occurring oxide of titanium, chemical formula TiO2.

You will find Ti02 in all kinds of paint, printing ink, plastics, paper, synthetic fibers, rubber, condensers, painting colors and crayons, ceramics, electronic components along with food and cosmetics.

Photocatalyst
Many studies have been published on the use of TiO2 as a photocatalyst for the decomposition of organic compounds. TiO2 is active under UV light

Photocatalytic activity (PCA) is the ability of a material to create an electron hole pair as a result of exposure to ultraviolet radiation. The resulting free-radicals are very efficient oxidizers of organic matter. Photocatalytic activity in TiO2 has been extensively studied because of its potential use in sterilization, sanitation, and remediation applications. The ability to control PCA is important in many other applications utilizing TiO2 including paint pigments and cosmetics that require low PCA.

Antimicrobial Coatings
The photocatalytic activity of titania results in thin coatings of the material exhibiting self cleaning and disinfecting properties under exposure to UV radiation. These properties make the material a candidate for applications such as medical devices, food preparation surfaces, air conditioning filters, and sanitaryware surfaces.

Anti-fogging glass.  Generally is moist air comes in contact with glass, small droplets of water are formed, and the glass becomes fogged.  On titanium dioxide coated glass, the water forms a continuous flat sheet, so that there is no fogging. Anti-fogging glass.
