Abstract
(Fe,Al)Ferrierite type zeolite was hydrothermally crystallized in a gel system of sodium aluminosilicate with ethylene glycol a nitrogen-free organic compound, as well as, ethylene diamine. The zeolite crystals obtained were characterized by X-ray diffractometry (XRD), thermal analysis (TGA–DTA), electron scanning microscopy (SEM), chemical analysis, N 2 adsorption/desorption at 77 K and 29Si–, 27Al–, 13C–, and 1H NMR spectroscopy. Fe atoms essentially occupy framework positions and rather high amounts of SiOH defect groups are present in the as-made samples.
