Abstract

La présente invention concerne un nanocatalyseur d'oxydation à écorce d'oxyde de cérium mésoporeux, et un procédé d'oxydation complète de monoxyde de carbone et d'hydrocarbure utilisant celui-ci. Plus particulièrement, la présente invention concerne un nanocatalyseur d'oxydation, et un procédé d'oxydation complète de monoxyde de carbone et d'hydrocarbure utilisant celui-ci, le nanocatalyseur présentant une structure cœur-écorce dans laquelle une écorce d'oxyde de cérium comportant des mésopores entoure un cœur obtenu par immobilisation de nanoparticules de métal précieux sur des nanoparticules sphériques. Ce catalyseur à nanoparticules comportant une écorce d'oxyde de cérium mésoporeux selon la présente invention présente un avantage en ce qu'un excellent taux de conversion est obtenu pendant l'oxydation complète du monoxyde de carbone et de l'hydrocarbure par comparaison avec un catalyseur classique comportant une écorce telle que de la silice mésoporeuse. De plus, il existe un avantage en ce, contrairement à un catalyseur utilisant un support en oxyde de cérium commun, une activité élevée est maintenue même après cuisson.
