含有4.82网层和螺-5结构单元的分子筛骨架构筑规则和结构设计
onstruction rules and structure prediction of zeolite frameworks containing 4.82 nets and spiro-5 building units
在已知分子筛中,有一些骨架结构是由4.82网层和螺-5为基本的结构单元构筑而成的,包括JOZ、NAB、WEI、LOV、RSN、VSV。这些分子筛骨架结构的区别主要在于4.82网层和螺-5结构单元的排列方式的不同。在此基础上,通过变换这两个结构单元的位置和连接方式,可以预测结构多样的假象分子筛骨架结构类型。同时,通过理论计算获得这些假想结构的骨架能量,并与已知分子筛结构相互比较。
4.82 nets and spiro-5 units have been found in several zeolite framework types, including JOZ, NAB, WEI, LOV, RSN, and VSV. The different arrangement of spiro-5 units between the 4.82 nets leads to different framework types. By varying the locations of the spiro-5 units between the 4.82 nets, a number of hypothetical zeolite structures with feasible framework energies have been predicted.
