Abstract:
This review article deals with a spectroscopic characterisation, including FTIR, UV-Vis-NIR and NMR, of acid and
redox microporous aluminophosphate catalysts with chabasite-related structure. These materials show high thermal and
hydrothermal stability, and for this reason are attractive catalysts for environmental application. An extended investigation
of acid SAPO-18 and SAPO-34, which are selective catalysts in methanol-to-olefins (MTO) and oxidative dehydrogenation
(ODH) of light alkanes processes, will be presented. These catalysts can also be used as supports for the preparation of
metal-containing molecular sieves for De-NOx reactions. Catalytic studies of NO oxidation to NO2 and N2O decomposition
performed on cobalt- and copper-containing materials will be illustrated and correlated to spectroscopic results.
