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 curvesandrespectively 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 inventionare more efficient.

Textile fibers having photocatalytic properties for degrading chemical or biological agents, method for preparing same and use thereof in photocatalysis

The invention relates to a photocatalyst comprising a &#x3b2;-SiC cellular foam and a photocatalytically active phase, deposited directly on said cellular foam or on an intermediate phase deposited on said cellular foam. The average size of the cells is between 2500 &#x3bc;m and 5000 &#x3bc;m. The foam can comprise nanotubes or nanofibers (particularly of carbon, SiC, and TiO) that consist of, or carry as an intermediate phase, a photocatalytically active phase.
