Abstract
The synthesis of Fe-MCM-22 zeolite is reported for the first time. Its stru cture and characteristics are similar to those of the MCM-22 zeolite. The a luminum is in a framework tetrahedral position in the [Fe,Al]-MCM-22 sample s. The white color of the samples, the increase of the Si-29 and Al-27 NMR linewidths with increasing Fe content and the constancy of the (Fe+Al)/u.c. values all suggest that Fe is also incorporated in tetrahedral position of the framework.
