Abstract
La présente invention concerne un sel de silicoaluminophosphate pour lequel la détérioration de la vitesse de réduction d'oxydes d'azote est faible, même quand il est exposé à une atmosphère contenant de l'humidité. Ce sel de silicoaluminophosphate comprend au moins un type de métal sélectionné dans le groupe constitué par des éléments du groupe VIIIB, des éléments du groupe IB et des éléments du groupe VIIB du tableau périodique, et possède une structure CHA et une structure AEI, la proportion de la structure AEI étant supérieure à 50 %. Dans ce sel de silicoaluminophosphate, l'au moins un type de métal des éléments du groupe VIIIB et des éléments du groupe IB du tableau périodique est de préférence le cuivre.
