Patent

CA 2695236

The invention relates to a method for manufacture of fine-particle, high- surface-area materials coated with inorganic nano particles, as well as the materials manufactured by said method, in particular catalysts for the heterogeneous catalysis. The method according to the invention is characterized by that the fine-particle high-surface-area material is contacted with a suspension of inorganic nano particles in a liquid medium, where the nano particles are bound to biopolymers and that if necessary the catalytically coated fine--particle high-surface-area material is dried.

L'invention concerne des procédés pour produire des matériaux à couche superficielle profonde, constitués de fines particules, revêtus de nanoparticules inorganiques, et les matériaux ainsi produits, notamment des catalyseurs servant à réaliser une catalyse hétérogène. Le procédé selon l'invention est caractérisé en ce que le matériau à couche superficielle profonde, constitué de fines particules est mis en contact avec une suspension constituée de nanoparticules inorganiques dans un milieu liquide et en ce que, éventuellement, le matériau à couche superficielle profonde, constitué de fines particules, revêtu par voie catalytique, est soumis à un séchage.
