Synthesis and characterization of SAPO-34 and MeAPSO-34 (Me= Fe, Ni and Sn) molecular sieves

Si substituted AlPO4-based molecular sieves with CHA structures including SAPO-34 were synthesized successfully from ?-Alumina as Alumina source, silicic acid as silica source, by hydrothermal treatment at the crystallization temperature of 473K in the presence of diethyl amine (DEA) as a template. Incorporation of metal to SAPO-34 frameworks leads to MeAPSO-34 molecular sieves. We synthesized MeAPSO-34 (Me=Fe, Ni and Sn) successfully. Prepared molecular sieves were characterized by various methods such as XRD, SEM, FT-IR. They were almost pure and completely crystallized.
