Frequently Asked Questions

What is Photo Catalytic Oxidation (PCO)?

Photocatalytic Oxidation (PCO) can be defined as a chemical reaction influenced or initiated by light that removes electrons from a catalyst and adds those electrons to a compound. This definition highlights the main ingredients that make photocatalytic air purification possible: a light source, a catalyst, and reactants.1
