Abstract

Los materiales catalíticos para la depuración de gases de escape de compuestos catalíticos comprenden catalizadores que contienen metales del grupo del platino (PGM) cuyo(s) componente(s) de PGM se proporciona(n) como nanopartículas y se fija(n) al óxido metal refractario, lo cual puede proporcionarse como un precursor. En la calcinación de los catalizadores, el PGM se fija térmicamente al soporte. Mediante el uso de dichos catalizadores, ventajosamente se puede lograr una excelente conversión de hidrocarburos y óxidos de nitrógeno.
