| Abstract: | Catalytic ammoxidation of propylene was studied using Fe2O3–MoO3/SiO2 catalysts, which have been prepared following a special method. Interaction of ammonia with the catalysts was studied by means of IR spectroscopy and gravimetrically using a McBain balance. Introduction of iron into MoO3/SiO2 catalysts modifies acidic as well as redox properties.
