摘要: 合成了新的Cr-ZSM-48型和V-ZSM-48型杂原子分子筛,并进行了结构表征,结果表明,Cr-ZSM-48、V-ZSM-48与全硅ZSM-48结构相同,Cr和V分别以+3和+4价态存在;杂原子以畸变四面体配位方式进入分子筛骨架。

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.
