Abstract
A correlation of the reaction rate over Fe-Beta catalysts with a concentration of specific isolated Fe3+ sites represented by an ESR signal at g ≈ 4.3 and by UV adsorption bands with λmax <300 nm was observed. Blocking zeolite cationic positions with Ca2+ and investigation of “Fe-free” Beta-zeolites confirmed the idea of isolated Fe complexes in cationic positions being active sites for NH3-deNOx.
