Abstract

Se describe un material catalizador para la oxidación de NO que comprende un portador catalizador que incluye un soporte de óxido de cerio-alúmina que tiene platino y, opcionalmente, paladio disperso en el soporte. Cuando existe paladio, la relación de platino con respecto al paladio en peso es al menos 1:1. La cantidad de óxido de cerio en el soporte se encuentra en el intervalo de 1 % a 12 % en peso. El material catalizador es útil para los métodos y sistemas de reducción de contaminantes de gases de escape de autos de motores de mezcla pobre.
