Title (EN) TRANSITION METAL CATALYST NANOPARTICLES AND USES THEREOF
(FR) NANOPARTICULES DE CATALYSEUR À MÉTAL DE TRANSITION ET LEURS UTILISATIONS
Abstract:
(EN) The present disclosure is directed to microparticles comprising carbon, wherein a plurality of nanoparticles are supported on the surface of the microparticle. The nanoparticles comprise at least one transition metal compound selected from the group consisting of transition metal carbides, transition metal nitrides, transition metal sulfides, transition metal phosphides, transition metal carbonitrides, transition metal sulfonitrides, transition metal carbosulfides, transition metal phosphocarbides, transition metal phosphonitrides, transition metal phosphosulfides, transition metal carbosulfonitrides, transition metal carbophosphonitrides, transition metal phosphosulfonitrides, transition metal carbophosphosulfonitrides, and interstitial derivatives thereof. The present disclosure is also directed to processes for preparing such microparticles and to polymer electrolyte membranes (PEMs) that comprise such microparticles, as well as to the use of such PEMs in fuel cells.
(FR) La présente invention concerne des microparticules comprenant du carbone, une pluralité de nanoparticules étant soutenues sur la surface de la microparticule. Les nanoparticules comprennent au moins un composé de métal de transition choisi dans le groupe constitué par des carbures de métal de transition, des nitrures de métal de transition, des sulfures de métal de transition, des phosphures de métal de transition, des carbonitrures de métal de transition, des sulfonimides de métal de transition, des carbocarbures de métal de transition, des phosphocarbures de métal de transition, des phosphonitrures de métal de transition, des phosphosulfures de métal de transition, des carbosulfonitrures de métal de transition, des carbophosphonitrures de métal de transition, des carbophosphosulfonitrures de métal de transition, et des dérivés interstitiels de ceux-ci. La présente invention concerne en outre des procédés de préparation de telles microparticules et des membranes électrolytiques de polymère (MEP) qui comprennent de telles microparticules, ainsi que l'utilisation de telles MEP dans des piles à combustible.
