A wide number of experimental techniques (ICP-AES, XRD, HRTEM, Al-27 MAS NMR, NH3-TPD, DRS UV-vis, HTTPR and EPR) have been applied to understand the metal exchange order effect on the composition, texture, structure, acidity and speciation of bimetallic materials. DRS UV-vis, H-2-TPR, EPR and HRTEM experiments conducted on Cu-Fe-ZSM5 and Fe-Cu-ZSM-5 allowed the identification of both isolated and clustered metal species differing in their amount, environment and degree of aggregation leading to a different catalytic behaviour of both catalysts.Reserva de todos los derechosSolid-state ion exchangeSelective catalytic reduction (SCR)NOZSM-5Characterization and NH3-SCR reactivity of Cu-Fe-ZSM-5 catalysts prepared by solid state ion exchange: The metal exchange order effectArtículo10.1016/j.micromeso.2017.10.051Abierto1873-3093
