Subject RIV: CF - Physical ; Theoretical Chemistry

Negligible activity in NO-NO2 equilibration and SCR of NOx by propane as well as benzene hydroxylation and N2O decomposition reactions was obtained over laboratory synthesized H-MFI, H-FER and H-BEA zeolites containing Fe with concentration below 50 ppm. The consequence of this evidenced role of such low levels of iron content, i.e. at level usually present in the commercial samples mostly used for the catalytic studies, and not considered in the analysis of the redox function of these systems, is discussed.
