Fe Species

Fe-MCM-36 zeolites are effective catalysts for high-temperature NH3-SCR – their activity is related to effective NO to NO2 oxidation over Fe2O3 species, while high N2-selectivity is attributed to dispersed Fe-species active in N2O decomposition.

ABSTRACTThermally stable alumina and zirconia pillared clays loaded with copper and cobalt cations and silver nanoparticles were synthesized. The structural and surface features of these nanosystems were studied and compared with those of bulk analogs -partially stabilized zirconias and γ-alumina loaded with the same active components. Specificity of the catalytic properties of nanocomposites in the reactions of nitrogen oxides reduction by propane, propylene and decane in the excess of oxygen appears to be determined both by the degree of interaction between pillars and active components and the type of reducing agent.
