Abstract[German]
Die Erfindung betrifft ein Verfahren zur Nachbehandlung von Platinlegierungskatalysatormaterial (6), umfassend die Schritte eines Durchführens (100) einer ersten Behandlung zum zielgerichteten Herauslösen von Übergangsmetall-Kationen aus dem Platinlegierungskatalysatormaterial (6) sowie eines Durchführens (200) einer zweiten Behandlung zum Anregen einer Neuordnung der Gitterstruktur des Platinlegierungskatalysatormaterials (6), wobei die zweite Behandlung eine zielgerichtete Temperierung des Platinlegierungskatalysatormaterials (6) umfasst.[English]
The invention relates to a method for post-treating platinum-alloy catalyst material (6), comprising the steps of carrying out (100) a first treatment for the targeted extraction of transition-metal cations from the platinum-alloy catalyst material (6), and carrying out (200) a second treatment for stimulating a rearrangement of the lattice structure of the platinum-alloy catalyst material (6), the second treatment comprising targeted temperature-control of the platinum-alloy catalyst material (6).[French]
L'invention concerne un procédé de post-traitement d'un matériau catalytique en alliage de platine (6), comprenant les étapes consistant à mettre en oeuvre (100) un premier traitement pour l'extraction ciblée de cations de métaux de transition à partir du matériau catalytique en alliage de platine (6), et à réaliser (200) un second traitement pour stimuler un réarrangement de la structure en treillis du matériau catalytique en alliage de platine (6), le second traitement comprenant une régulation de température ciblée du matériau catalytique en alliage de platine (6).
