Abstract
(EN)
Described herein are filter elements comprising a substrate with a composite layer on a surface of the substrate in which the composite layer comprises nanoparticles comprising a first metal, a first metal oxide or a combination thereof; and a layer comprising a second metal, second metal oxide or combination thereof between the nanoparticles on the surface of the substrate. Methods of forming such filter elements are also described along with filters incorporating these filter elements, methods of treating a fluid using the filter element and methods of regenerating the filter element. Preferred first and second metals are Fe, Ni, Ag, Au, Cu, Zn, Pt, Co, Ce or Al.

La présente invention porte sur des éléments filtrants comprenant un substrat doté d'une couche composite sur une surface du substrat, la couche composite comprenant des nanoparticules comprenant un premier métal, un premier oxyde métallique ou une association de ceux-ci ; et une couche comprenant un second métal, un second oxyde métallique ou une association de ceux-ci entre les particules disposées sur la surface du substrat. L'invention porte également sur des procédés de formation de tels éléments filtrants ainsi que sur des filtres incorporant ces éléments filtrants, sur des procédés de traitement d'un fluide utilisant l'élément filtrant et sur des procédés de régénération de l'élément filtrant. Les premier et second métaux préférés sont Fe, Ni, Ag, Au, Cu, Zn, Pt, Co, Ce ou Al.
