Abstract

Variable temperature high resolution Si-29 magic angle spinning NMR spectroscopy has been used to study the thermal behaviour of the aluminosilicate zeolite ferrierite. Three samples of have been prepared with varying quantities of framework aluminium using a fluoride based synthesis. Spectra collected between 293 and 500 K have shown that aluminosilicate ferrierite shows a displacive phase transition between the low temperature and high temperature phases of the material. A comparison of the spectra for the three samples shows that the quantity of framework aluminium has a significant effect on the phase transition temperature. (c) 2006 Elsevier SAS.
