Infrared light active photocatalyst for the purification of airborne indoor pollutants

Abstract In photocatalysis, most of the catalysts area active either for UV or visible radiations and infrared active catalysts are rare. In this investigation, Ag 2 O/Ag/TiO 2 catalyst was synthesized and successfully applied for the degradation of gaseous phenol under IR irradiation. As the photodegradation described in this report involves low energy IR photons under ambient indoor conditions, the catalytic system can be applied for the degradation of common airborne pollutants found in indoors.
