Reducibility and catalytic activity in propane oxidation was studied for the Cu ions exchanged in zeolites of structural types ZSM-5(MFI), ferrierite(FER) and erionite(ERI) with different Cu/Al/Si compositions and Na+ or H+ ions present as co-cations. The Cu ions balanced by a single ALO2-entity, being most populated in zeolites with high Cu loading and in zeolites with low concentration of aluminium in the framework are suggested to be those easily reducible, and exhibiting high oxidation activity.
