Abstract
The reducibility of FeIII to FeII in H2 increased in the order FeS/ZÂ <Â Fe/ZCVDÂ <Â Fe/Zi. In the C3H6Â +Â O2 reaction, the catalytic activity for C3H6 oxidation increased in parallel with the reducibility. In the NOÂ +Â C3H6Â +Â O2 reaction, the selectivity to CO2 (rather than to CO) increased in parallel with the reducibility. By contrast, the selectivity of C3H6 towards NO rather than O2 increased in the reverse order. These results suggest that the catalytic activity and selectivity of the various samples depend on the chemical behaviour of the FeIII/FeII redox couple.
