As a result of testing of a series of Fe-containing catalysts based on different types of zeolite structure, zir- conia and binary support (zeolite + ZrO2) in the reaction of nitrogen( I) oxide decomposition it was found that the most active zeolite-based catalysts are characterized by the presence of strong acidic sites on their surface.

Key words nitrogen(I) oxide, decomposition, zeolites, zirconia, activity, acidity.
