Abstract
The combined XAS/XRD technique has been used to investigate the stability o
f the microporous structure during calcination process for a series of ZnAP
SO-44 materials. Incorporation of large amounts of Zn is found to produce m
aterials that are unstable upon removal of the structure directing organic
template molecule. However, simultaneous incorporation of Si is found to in
crease the thermal stability of the materials, yielding catalysts that are
well suited for acid catalysed reactions.
