SO2-promoted catalytic N2O removal over iron zeolites.
SO(2) promotes the rate of N(2)O removal over Fe-zeolites more efficiently than other reducing agents (NH(3)) and promoters (NO); the effect of SO(2) 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.
