Abstract
La presente descripción provee en general catalizadores, artículos catalíticos y sistemas catalizadores que comprenden tales artículos catalíticos. En particular, la composición catalizadora comprende una zeolita que posee una estructura de cristal de chabazita (CHA) con intercambio iónico con hierro y cobre. Se proveen también métodos para preparar y usar la composición catalizadora así como también sistemas de tratamiento de emisiones que comprenden un artículo catalizador recubierto con la composición catalizadora. El articulo catalizador presente en dichos sistemas de tratamiento de emisiones es útil para catalizar la reducción de óxidos de nitrógeno en el escape de gases en presencia de un reductor.
