Ion exchanged zeolite

WebXRD data confirmed the purity and structure of the Y/USY or ZSM-5 zeolites. The nitrogen and ammonia sorption results indicated that the materials were highly porous and acidic. The metallic active phase was found in the form of cations in ion-exchanged zeolites and in the form of nanoparticle metal oxides in sonochemically prepared catalysts. WebZeolites are aluminosilicate solids bearing a nega charged honeycomb framework are micropores into which molecules may be adsorbed for environmental decontamination, and for catalyse gas reactions.
