Photocatalytic Oxidation, also known as PCO, it’s a chemical effect produced when a light source penetrates a surface that works as a semiconductor material, best known as a photocatalyst.

The photocatalyst absorbs the UV lights and creates oxygen particles such: OH•, OH-, O2-•, HO2, thanks to a mix of noble metals, where Titanium Dioxide (TIO2) works as the key element.

Titanium Dioxide it’s a non-toxic substance, and its high level of photoactivity, good behaviour, and stability, added to its low cost, converts it into a very efficient substance.
