| Abstract: In this paper, Sapo-5, Tapo-5,Bapo-5 hetero-atom aluminophosphate molecular sieves were synthesized by Vapor-Solid phase replacement. The crystal morphology, ability of adsorption, thermal stability of them were studied. The structure of aluminophosphate hetero-atom molecular sieves has been also researched with ESR, XPS, XEP, IR, MAS. NMR and XRD. The results show that titanium, silicon, boron were introduced to the framework of molecular sieves. |
