Technology is some 30 years old but popular in commercial application only recently,Works by catalyzing oxidation of contaminants in contact with a semi-conductor which is in a chemically reactive state brought about by UV or sunlight.TiO2 is usually used as the catalyst; hydroxyl radicals as intermediate.Effectiveness depending on reaction surface, decrease if dust particles built up

Photo-Catalytic Oxidation (PCO)Available Technologies

Relatively new technology in IAQ applicationsPlasma is highly energized gaseous state with gas molecules dissociated into ions, radicals, singlet atoms, and electrons.Work by the ability of plasma to destroy the carbon-carbon bonds of organic contaminants.A natural force of re-generation - lightningCan be created by high voltage Corona Discharge - Hot Plasma; or by photon energy from UV light Cold Plasma or PhotoPlasma.PlasmaAvailable Technologies
