Abstract

Abstract: Cr-ZSM-48 and V-ZSM-48 type hetero-atom molecular sieves were synthesized and their structures were characterized by many physicochemical methods. The results show that Cr-ZSM-48, V-ZSM-48 and Silica-ZSM-48 are isostruclural. Cr and V exist as three-valence and four-valence ions respectively. The hetero-atoms are introduced into the framework of the molecular sieves in distortion-al tetrahedral coordination.

Key words: Chromium, Vanadium, ZSM-48, Systhesis, Structure
