[交流] 有MCM-56吗?

听说MCM-56和ZSM-5的结构一样。
真是这样吗?

什么沸石结构与ZSM-5接近或类似?

那肯定不一样的
MCM-56和MCM-2结构相近,只是层状间距更紧凑点
类似石墨结构
而ZSM-5是MFI结构,就像三根空心棍棍摆了个类似三位坐标轴类形式
不过不完全成直角

In recent years, many modifications in the synthesis procedure and catalytic applications of MCM-22 have been published [1–4], while little is reported about the properties of MCM-56, especially the catalytic applications. Fung [4] first reported the synthesis of MCM-56. As MCM-56 and MCM-22 all share the MWW structure[5], MCM-56 exhibited some similarities with MCM-22, including the sinusoidal network channel and a large number of 12 MR cups exposed to the crystal exterior [6]. MCM-56 can be thermally treated without affecting its layered structure, while the structure of as-made MCM-22 changed markedly after calcinations. Large supercages with an inner diameter of approximately 0.71 nm and a height of 1.82 nm appear in calcined MCM-22 [7].
