Abstract

La présente invention concerne un produit de revêtement à propriétés photocatalytiques comportant des particules de dioxyde de titane TiO2, caractérisé en ce qu'il comporte des particules TiO2 qui sont de taille supérieure à des nanoparticules et constituent des moyens de réaction par photocatalyse sous un éclairage intérieur. Il a été montré de manière surprenante que des mircroparticules de TiO2 peuvent réagir à la lumière d'un éclairage intérieur comprenant peu d'UV, avec de très bonnes performances au regard de la dégradation de polluants du type NOx ou formaldéhyde.The present invention relates to a coating product with photocatalytic properties comprising particles of titanium dioxide TiO2, characterized in that it comprises TiO2 particles which are larger than nanoparticles and constitute reaction means by photocatalysis under interior lighting. . It has been surprisingly shown that TiO2 mircroparticles can react to the light of indoor lighting comprising little UV, with very good performance with regard to the degradation of pollutants of the NOx or formaldehyde type.
