Briefly, Photocatalytic oxidation (PCO), as the name suggests, employs ultraviolet light photons and a catalyst: a proprietary mixture of various catalytic particles adhered to a target surface. As photons from the UV light shine on the catalyst, a reaction occurs creating ions that decontaminate air and surfaces. Photocatalytic oxidation (PCO) is a cost-effective technology for VOCs removal, compared with adsorption, biofiltration, or thermal catalysis method. Development of active photocatalyst systems is crucial for the PCO reaction.
