Epitaxial FAU zeolite films were achieved on micrometer-sized EMT support crystals using a two-step synthetic procedure, in which EMT support crystals with hexagonal-platelet morphology, were added to a synthesis gel for the crystallization of an FAU

Two solid-state NMR methods are proposed to study the degree of silylation of MCM-41 with trimethylchlorosilane (TMCS). Both 29 Si MAS NMR and 1 H MAS NMR provide an accurate estimation of the amount of trimethylsilane attached to MCM-41. A silylatio

The MQ MAS NMR is used to evaluate the real, individual line shape of the Al signals in the 1D 27Al MAS NMR spectrum of zeolite materials. By the application of these real line shapes, an improved deconvolution of the 1D MAS NMR spectrum is achieved.
