Abstract
(EN)
The present invention relates to a metallic nanoparticle catalyst and, more specifically, to a porous catalyst having metallic nanoparticles embedded in a porous oxide support and to a method for preparing the porous catalyst. To this end, a porous catalyst composition having metallic nanoparticles of the present invention comprises: an oxide matrix structure having mesopores and micropores; and metal or metal oxide nanoparticles embedded in the oxide matrix structure having mesopores and micropores. A method for preparing a porous catalyst composition having metallic nanoparticles of the present invention comprises the steps of: covering metallic nanoparticles containing at least any one of metals and metal oxides with a stabilizer to stabilize the metallic nanoparticles and then binding a polymer to the surface of the metallic nanoparticles to functionalize the metallic nanoparticles; mixing an oxide precursor in a solution in which the functionalized metal nanoparticles and an activator are mixed and dispersed, thereby synthesizing a metallic nanoparticle dispersion embedded in a porous oxide support; and firing the metallic nanoparticle dispersion. Thus, metallic nanoparticle catalysts having high activity even at low temperatures are realized.

La présente invention concerne un catalyseur à nanoparticules métalliques et, plus spécifiquement, un catalyseur poreux ayant des nanoparticules métalliques incorporées dans un support d'oxyde poreux et un procédé de préparation du catalyseur poreux. A cet effet, une composition de catalyseur poreux ayant des nanoparticules métalliques de la présente invention comprend : une structure de matrice d'oxyde ayant des mésopores et des micropores; et des nanoparticules de métal ou d'oxyde métallique incorporées dans la structure de matrice d'oxyde ayant des mésopores et des micropores. Un procédé de préparation d'une composition de catalyseur poreux ayant des nanoparticules métalliques de la présente invention comprend les étapes consistant à: recouvrir des nanoparticules métalliques contenant au moins l'un quelconque des métaux et des oxydes métalliques avec un stabilisant pour stabiliser les nanoparticules métalliques, puis lier un polymère à la surface des nanoparticules métalliques pour fonctionnaliser les nanoparticules métalliques; à mélanger un précurseur d'oxyde dans une solution dans laquelle les nanoparticules métalliques fonctionnalisées et un activateur sont mélangés et dispersés, ce qui permet de synthétiser une dispersion de nanoparticules métalliques incorporée dans un support d'oxyde poreux; et à cuire la dispersion de nanoparticules métalliques. Ainsi, des catalyseurs à nanoparticules métalliques ayant une activité élevée même à basses températures sont réalisés.
