What is “Photocatalyst”?

“Photocatalyst” can decompose various bacteria ,virus and gas odors then change to safety substance “CO2” and “Water”.
This chemical reaction occurs only under lights.

Mechanism

Defeat virus / bacteria by high oxidizing power !

Under light irradiation, chemical reactions occurs on the surface that have photocatalyst treatment. First, water on the surface are oxidized and change to hydroxyl radical (・OH). And oxygen on the surface also becomes free radical(.O2-)

This is the mechanism of photocatalyst. It has very high oxidative decomposition, and make various bacteria and virus, VOC gas change to safety substance(CO2 and water).
