Title (EN) ULTRASOUND-ASSISTED DEPOSITION OF A METAL-CONTAINING ACTIVE SPECIES OVER A NON-POROUS SUPPORT FOR PRODUCTION OF A CATALYST
(FR) DÉPÔT ASSISTÉ PAR ULTRASONS D'UNE ESPÈCE ACTIVE CONTENANT DU MÉTAL SUR UN SUPPORT NON POREUX POUR LA PRODUCTION D'UN CATALYSEUR
Abstract:
(EN) Processes for ultra-sound assisted deposition of an extraneous specie over a support having a specific surface area of less than 40 m2.g-1. Immersion of the support is performed within a liquid medium containing the extraneous specie in dissolved state. Acoustic cavitation is generated within the liquid medium and proximate to the immersed support via ultrasonic waves, causing deformation of a surface of the immersed support and creating additional specific surface sites wherein the extraneous specie is deposited upon physical and/or chemical bonding therewith. A material comprising a non-porous core and an external layer of an extraneous specie, the extraneous specie being selected to confer or enhance properties including catalytic activity, hydrophobicity, adhesion, wettability, corrosion resistance, mechanical resistance, thermal resistance, elasticity, aesthetic appeal or a combination thereof.
(FR) Procédés de dépôt assisté par ultrasons d'une espèce étrangère sur un support ayant une surface spécifique inférieure à 40 m2.g-1. L'immersion du support est réalisée dans un milieu liquide contenant l'espèce étrangère à l'état dissous. Une cavitation acoustique est générée à l'intérieur du milieu liquide et à proximité du support immergé par l'intermédiaire d'ondes ultrasonores, provoquant la déformation d'une surface du support immergé et créant des sites de surface spécifiques supplémentaires, l'espèce étrangère étant déposée lors d'une liaison physique ou chimique avec celle-ci. Un matériau comprenant un noyau non poreux et une couche externe d'une espèce étrangère, l'espèce étrangère étant sélectionnée pour conférer ou améliorer des propriétés comprenant une activité catalytique, l'hydrophobicité, l'adhérence, la mouillabilité, la résistance à la corrosion, la résistance mécanique, la résistance thermique, l'élasticité, l'attrait esthétique ou une combinaison de ceux-ci.
