Abstract
Fe-MCM-36 zeolites are effective catalysts for high-temperature NH<sub>3</sub>-SCR – their activity is related to effective NO to NO<sub>2</sub> oxidation over Fe<sub>2</sub>O<sub>3</sub> species, while high N<sub>2</sub>-selectivity is attributed to dispersed Fe-species active in N<sub>2</sub>O decomposition.
