FOTOCIDE®

What is FOTOCIDE® Photocatalytic Oxidation Technology?

Air Treatment / Water Treatment System employing Fotocide® Photocatalytic Oxidation Technology (PCO) provides the most efficient way to remove bacteria and pollutants from air / water. The PCO core system involves the action of a low UV energy, activating a Titanium Dioxide (TiO2) based catalyst surface which, in the presence of air / water, generates hydroxyl radicals (OH.) that oxidize pollutants, bacteria and viruses and convert them into harmless carbon dioxide and water.

　

Why Choose Fotocide® nano-coating technology for PCO?

Applying Fotocide® nano-coating technology, a catalytic surface for PCO is generated, allowing for the formation of a homogeneous high density and superior catalysis oxidative potency Titanium Dioxide TiO2 anatase to be sequestered tightly onto a solid substratum. The resulting catalytic surface provides the platform for maximum per unit area efficiency for the elimination of pollutants as well as pathogens. Furthermore, the resulting nano-coated TiO2 are tightly bound to the catalytic surface, providing it with a distinctive self-cleaning and non-sticky characteristic.

　

PCO Cleaning Principle

        Exposure to ultraviolet rays

When a photocatalyst surface is exposed to UV light, energized electrons will break free of the TiO2 coating. These electrons leave behind positively charged pockets called, “positive holes”.

         Creation of Hydroxyl radicals

The positive holes vigorously attract hydroxide ions (OH-) from ambient air / water. The positive holes then take an electron from an OH- turning it into an extremely unstable OH radical (OH.).

        Breaking up organic compounds

To stabilize themselves, the OH radicals take electrons from nearby organic compounds and pollutants. This action breaks up the pollutants; thus decomposing them into harmless carbon dioxide and water that are released into the air.
