  • Textile fibers having photocatalytic properties for degrading chemical or biological agents, method for preparing same and use thereof in photocatalysis
    Patent number: 9441324
    Abstract: The invention relates to textile fibers at least partially covered with a nanometric-sized semiconducting material having photocatalytic properties for degrading chemical compounds, in particular chemical or biological agents, wherein said semiconducting material is in the form of nanostructure or nanocomposites with a one-dimensional morphology. The textile fibers can be used for application in the military, medical, and civilian domains, etc. The curves 60 and 62 respectively show the photocatalytic degradation of organic compounds at the surface of textile fibers covered with nanostructures or nanocomposites having a one-dimensional morphology according to the invention, and nanoparticles having a granular morphology according to the prior art. The nanostructures are nanocomposites of the invention 60 are more efficient.

  • CATALYST FOR THE PHOTOCALYTIC TREATMENT OF GASEOUS MEDIA CONTAINING CARBON MONOXIDE
    Publication number: 20130022524
    Abstract: The present invention relates to catalytic compositions for, inter alia, the photocatalytic oxidation of CO, including: a substrate including, at least at a surface thereof, titanium oxide; and, deposited on the titanium oxide on the surface of the substrate, a metal mixture containing: platinum, at least partially in the metal state; and palladium and/or nickel, at least partially in the metal state. More specifically, the invention relates to the use of said compositions for treating gaseous media including CO and organic pollutants, for example indoor air in inhabited buildings or vehicles.
