A Multi-Dimensional Microporous Silicate That Is Isomorphous to Zeolite MCM-68

摘要

Zeolites with large pores and multi-dimensional channel systems allow the diffusion of large molecules inside the pores.The number of zeolites with such characteristics is still limited,however,therefore the synthesis of new large-pore,multi-dimensional zeolites remains important.MCM-68(MSE topology)is a new type of multi-dimensional zeolite with a 12X10X10-membered ring(MR)pore system where a 12-MR straight channel intersects with two independent twisted 10-MR channels.This material also contains a super-cage(18X12-MR)that is accessible only through the 10-MR pores.
