摘要: A high surface area temperature stable Iron bidimensional zeolitic material of 14(A) basal spacing was prepared using acetato and acetyl acetonate complexes iron. The decreases with calcination the passes through a maximum at 350°C. These materials were characterized by Mossbauer, ESCA, IR, CHN thermal analysis. results indicated that complex does not interact clay as such but is hydrolysed in solution before ion exchanging. This species polymerized to yeild polyhydroxy cations probable speculated. general consideration about mechanism formation pillars also discussed. Mossbauer iron highly dispersed form these material. ESCA suggested spin +3 state octahedral coordination. It shown it possible prepare bimetallic system containing Cr Fe.
