Title (EN) CATALYST
(FR) CATALYSEUR
Abstract:
(EN) A process for preparing a catalyst material, said catalyst material comprising a support material, a first metal and one or more second metals, wherein the first metal and the second metal(s) are alloyed and wherein the first metal is a platinum group metal and the second metal(s) is selected from the group of transition metals and tin provided the second metal(s) is different to the first metal is disclosed. The process comprises depositing a silicon oxide before or after deposition of the second metal(s), alloying the first and second metals and subsequently removing silicon oxide. A catalyst material prepared by this process is also disclosed.
(FR) L'invention concerne un procédé de préparation d'un matériau catalyseur, ledit matériau catalyseur comprenant un matériau support, un premier métal et un ou plusieurs seconds métaux, le premier métal et le ou les seconds métaux étant alliés, le premier métal étant un métal du groupe du platine, le ou les seconds métaux étant choisis dans le groupe des métaux de transition et de l'étain à condition que le ou les seconds métaux soient différents du premier métal. Le procédé consiste à déposer un oxyde de silicium avant ou après dépôt du ou des seconds métaux, à allier les premier et second(s) métaux et à éliminer ensuite l'oxyde de silicium. L'invention concerne également un matériau catalyseur préparé par ce procédé.
