Abstract[English]
-SCR) comprising an active phase comprising palladium and nickel, and a support comprising titanium dioxide, the palladium content being between 0.001 and 8% by weight of palladium element, the nickel content being between 1 and 20% by weight of nickel element based on the total weight of the catalyst, characterised in that: - the number-average diameter of the palladium particles is between 0.5 and 5 nm; and - the nickel particles are distributed across two distinct populations: a first population of particles having a number-average diameter between 2.5 and 6 nm, and a second population of particles having a number-average diameter between 7 and 12 nm.[French]
-SCR) comprenant une phase active comprenant du palladium et du nickel, et un support comprenant du dioxyde de titane, la teneur en palladium étant comprise entre 0,001 et 8% en poids en élément palladium, la teneur en nickel étant comprise entre 1 et 20% en poids en élément nickel par rapport au poids total du catalyseur, caractérisé en ce que : - le diamètre moyen en nombre des particules de palladium est compris entre 0,5 et 5 nm; et - les particules de nickel sont réparties dans deux populations distinctes : une première population de particules dont le diamètre moyen en nombre est compris entre 2,5 et 6 nm, et une deuxième population de particules dont le diamètre moyen en nombre est compris entre 7 et 12 nm.
