The Science of TiO2 Photocatalytic Oxidation (PCO).
Titanium Dioxide, also known as Titania, is the naturally occurring oxide of Titanium
(chemical formula TiO2). Titanium Dioxide is considered a safe substance and harmless
to humans. It is commonly used in ceramics, condensers, cosmetics, crayons, electronic
components, food (as E171), paint, printing ink, plastics, paper, rubber and synthetic
fibers. Many studies have been published on the use of titanium dioxide as a photocatalyst
for the decomposition of organic compounds. After illumination by light, titanium
dioxide produces hydroxyl radicals, which react with the organic matter in the air
to form non-
The photocatalytic properties of TiO2 can be brought to good use in the following five major functions;
Air Purification Removes Ethylene, Formaldehyde, NOx, Particulate Matter (PM), SOx,and VOCs.

Bromodichloromethane, Dibromochloromethane, Tetrachloroethene, Tribromomethane (bromoform), Trichloromethane(chloroform) and many other harmful substances...Turn contaminated water into potable grade using the photocatalytic properties inside clear distillation tubes or pipes or flatbed techniques. (which can also be utilised instead of using a basic TiO2 slurry and the associated recovery costs).
