Abstract

L'invention concerne deux tamis moléculaires d'aluminosilicate ayant des structures de pores ultra-grandes, désignées NJU120-1 et NJU120-2. La composition chimique schématique de l'état tel que synthétisé des tamis moléculaires est : rROH:a(OH-ou F-):xAl 2O 3:SiO 2:wH 2O, et la composition chimique schématique après calcination est : (HAlO 2) x · SiO 2. Après calcination de NJU120-1, la structure d'ossature composée d'un tétraèdre T(Si, Al)O 4 de celle-ci a un système de canal de pores tridimensionnel cyclique à 22 × 10 × 10 chaînons. Après calcination de NJU120-2, la structure d'ossature composée d'un tétraèdre T(Si, Al)O 4 de celle-ci a un système de canal de pores tridimensionnel cyclique à 22 × 12 × 10 chaînons. Les tamis moléculaires sont raisonnablement conçus, sont des matériaux de tamis moléculaire à pores ultra-grands, entièrement connectés, à haute teneur en silicium ou en silicium pur, exempts de germanium, et ont une valeur d'application pratique très importante dans des zones comprenant la catalyse, la séparation par adsorption, etc.
