Abstract
The decomposition of platinum and palladium tetrammine faujasite X has been studied by temperature-programmed desorption (t.p.d.) spectroscopy, differential thermal analysis and derivative thermogravimetry. Well resolved t.p.d. spectra allowed the deduction of a detailed mechanism with respect to autoreduction, ammonia evolution and the reaction of ammonia with acid sites. Characteristic differences observed between the palladium and platinum samples are related to the lower stability of the palladium tetrammine complexes within the faujasite matrix.Keywords
