Title (EN) NOX-TRAPPING CATALYST HAVING NON-PLATINUM-GROUP-METAL NOX-TRAPPING LAYER
(FR) CATALYSEUR DE PIÉGEAGE DE NOX AYANT UNE COUCHE DE PIÉGEAGE DE NOX DE MÉTAL DU GROUPE NON PLATINE
Abstract:
(EN) Disclosed is a NOx-trapping catalyst having a non-platinum-group-metal NOx-trapping layer, which contains a transition metal, particularly manganese, able to maintain NOx-trapping performance while decreasing the amount of expensive platinum-group metal.
(FR) L'invention concerne un catalyseur de piégeage de NOx ayant une couche de piégeage de NOx de métal du groupe non platine, qui contient un métal de transition, en particulier du manganèse, apte à maintenir des performances de piégeage de NOx tout en diminuant la quantité de métal du groupe platine onéreux.
