Iron antimony oxide selective oxidation catalysts - an inelastic neutron scattering study

The inelastic neutron scattering spectra of allyl iodide (3-iodopropene, CH 2=CHCH2I) and allylpalladium chloride, and allyl iodide dosed onto activate d iron(III) oxide and iron antimonate catalysts at room temperature have be en determined to characterise the adsorbed allyl species. The spectra are e nergy loss vibrational spectra in the range 16-4000 cm(-1). Allyl iodide is not decomposed on the surface and interacts through the localised C=C bond , more strongly with iron antimonate than with iron(III) oxide.
