About Photocatalystic Division

What is photocatalyst technology?

“Photocatalyst” is a general definition of a substance that triggers the change in a rate of chemical reaction without being altered or consumed by the reaction itself. A good example of such a reaction would be natural photocatalysis of leaves.

Photosynthesis is a chemical process that coverts carbon dioxide into organic compounds, especially starch, using the energy from sunlight. One of the most widely used substances in the process is oxidized titanium. Our product lineup utilizes the method radiating oxidized titanium coated ceramic units with 380nm wavelength ultraviolet light which results in eliminating viruses and unpleasant odors.

How our photocatalyst technology works

How our photocatalyst technology works-IMAGE

When TiO2 unit is subjected to 380nm ultraviolet light radiation, a electron is released from its’ surface and electron hole is generated. These photo-generated electron-hole pairs facilitate oxidation-reduction reactions between oxygen from air and hydroscopic water on oxidized TiO2 surface. This results in formation of ‘OH hydroxyl radical and superoxide anion – an extremely potent substance capable of eliminating viruses and unpleasant odors.

Practical application of our deodorizing device

Practical application of our deodorizing device-IMAGE

Units made of porous ceramic material coated with oxidized titanium are installed on our deodorization products. The air running through the device is purified and deodorized by the oxidation-reduction reactions.
