Abstract[German]
Die Erfindung betrifft ein Verfahren zur Nachbehandlung von Platinlegierungskatalysatormaterial (6), umfassend die Schritte eines Lösens (100) des Platinlegierungskatalysatormaterials (6) in einem Lösungsmittel (4), eines Rührens (200) des gelösten Platinlegierungskatalysatormaterials (6) innerhalb eines Reaktionsgefäßes (2), eines Zuführens (300) eines ersten Gases (G1) und eines zweiten Gases (G2) in das Reaktionsgefäß (2) zu dem gelösten Platinlegierungskatalysatormaterial (6), wobei das erste und das zweite Gas (G1, G2) alternierend zu dem gelösten Platinlegierungskatalysatormaterial (6) zugeführt werden und wobei ein platinhaltiges Salz zugegeben wird.[English]
The invention relates to a method for the post-treatment of a platinum alloy catalyst material (6), having the steps of dissolving (100) the platinum alloy catalyst material (6) in a solvent (4), stirring (200) the dissolved platinum alloy catalyst material (6) within a reaction vessel (2), and supplying (300) a first gas (G1) and a second gas (G2) to the platinum alloy catalyst material (6) in the reaction vessel (2), the first and second gas (G1, G2) being alternately added to the dissolved platinum alloy catalyst material (6), and a platinum-containing salt being added.[French]
L'invention concerne un procédé de post-traitement de matériau catalyseur en alliage de platine (6), le procédé comprenant les étapes consistant à dissoudre (100) le matériau catalyseur en alliage de platine (6) dans un solvant (4), à agiter (200) le matériau catalyseur en alliage de platine (6) dissous à l'intérieur d'une cuve de réaction (2), et à fournir (300) un premier gaz (G1) et un deuxième gaz (G2) au matériau catalyseur en alliage de platine (6) dans la cuve de réaction (2), les premier et deuxième gaz (G1, G2) étant ajoutés en alternance au matériau catalyseur en alliage de platine (6) dissous, et un sel contenant du platine étant ajouté.
