Abstract:
(EN) The present invention relates to a method for obtaining metal oxide nanoparticles dispersed on fibres, which comprises preparing a stable gel from nanoparticle precursors, submerging the fibres in the stable gel, and subjecting the fibres to a hydrothermal treatment to coat same uniformly with the nanoparticles. The fibres obtained are used in the degradation of organic pollutants.
(FR) La présente invention se rapporte à un procédé d'obtention de nanoparticules d'oxydes métalliques dispersées sur des fibres qui consiste à préparer un gel stable à partir de précurseurs de nanoparticules, immerger les fibres dans le gel stable et soumettre à un traitement hydrothermique jusqu'à recouvrir les fibres avec les nanoparticules de manière homogène. Les fibres obtenues sont employées dans la décomposition de contaminants organiques.
