Abstract

SO₂ promotes the rate of N₂O removal over Fe-zeolites more efficiently than other reducing agents (NH₃) and promoters (NO); the effect of SO₂ as selective reductant is independent of the framework type and composition, preparation method, and iron content, suggesting that its occurrence is not determined by a highly specific iron speciation.
