Patent

CA 2219913

The present invention addresses organic pollutant removal from enclosed environments such as a room or within a vehicle. A photocatalytic semiconductor coating located on the interior surface of a window or windshield is illuminated with UV light, thereby dissociating water on the surface thereof to form hydroxyl radicals. These hydroxyl radicals then oxidize organic pollutants adsorbed to the coating.

L'invention concerne l'élimination de polluants organiques en milieu fermé, par exemple dans une pièce ou dans un véhicule. Un revêtement semi-conducteur photocatalytique placé sur la surface intérieure d'une fenêtre ou d'un pare-brise est éclairé par des rayons ultraviolets, ce qui conduit à la dissociation de l'eau en surface et à la formation de radicaux hydroxyles. Ces radicaux hydroxyles oxydent alors les polluants organiques adsorbés par le revêtement.
