The exchange … 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.
WebXRD analysis also showed the occurrence of some isomorphic substitution phenomena where the Al 3+ ions of the clinoptilolite framework were replaced by exchanged Pb 2+ cations in the course of the ion exchange reaction. This mechanism was instead less evident in the patterns of the samples doped with Cd 2+ and Zn 2+ cations. 展开
