Europium was introduced into K'-exchanged Y-zeolite (K-Y) by impregnation from an ammoniacal solution of the metal. The catalytic properties of the zeolite were examined by the isomerization of 2,3-dimethylbut-1-ene to 2,3-dimethylbut-2-ene and the Michael reaction of cyclopent-2-enone with dimethy
Depending on preparation conditions, two types of Fe(lll) species were found (a cationic and a hydrated oxide form) and characterized in Fe(III)N H4-Y zeolites with iron,content in the range 0.3-5.8 wt %. These two forms were found to differ mutually, as well as from separate Fe20 3 phase, as far as
