Title (EN) METHOD FOR 'IN SITU' DEPOSITION OF MICRO- AND NANOSTRUCTURED OXIDES ON A POROUS SUPPORT
(FR) PROCEDE DE DEPOT 'IN SITU' D'OXYDES A MICROSTRUCTURES ET A NANOSTRUCTURES SUR UN SUPPORT POREUX
Abstract: front page image
(EN)Method for 'in situ' deposition of micro- and nanostructured oxides on a porous support The present invention provides a method for the deposition of an oxide belonging to the group which includes cerium oxide (or other rare earth oxides), vanadium oxides, alkaline metal (such as potassium, cesium, etc) oxides, alkaline-earth metal (such as calcium, barium, etc.) oxides as well as mixed ox- ides of the above mentioned elements on a porous support made of a ceramic material. The method is characterized in that said oxide is synthesized 'in situ' on the support by means of a combustion process (combustion synthesis) starting from a water solution containing the precursors of the oxide. The process is applied in particular to the production of cata- lytic devices for the abatement of pollutants.
(FR)L'invention porte sur un procédé de dépôt « in situ » d'oxydes à microstructures et à nanostructures sur un support poreux, ainsi que sur un procédé de dépôt d'un oxyde appartenant au groupe contenant un oxyde de cérium (ou autres oxydes de terres rares), des oxydes de vanadium, des oxydes de métal alcalin (tel du potassium, césium, etc.), des oxydes de métal alcalino-terreux (tel du calcium, baryum, etc.) ainsi que des oxydes mélangés des éléments susmentionnés sur un support constitué d'un matériau céramique. Ce procédé se caractérise par le fait que cet oxyde est synthétisé « in situ » sur le support au moyen d'un procédé de combustion (synthèse de combustion) à partir d'une solution aqueuse contenant les précurseurs de l'oxyde. Ce procédé s'utilise notamment dans la fabrication de dispositifs catalytiques pour la réduction de polluants.
