Abstract
Abstract In this work, studies of Fe 3 (CO) 12 and a mixture of Fe 3 (CO) 12 and Ni (acac) 2 impregnated in Al 2 O 3 were undertaken using Mossbauer and i.r. spectroscopies. In freshly prepared samples, low oxidation species were shown to be present. After thermal decomposition, the data indicate the appearance of aluminum compounds of Fe II and Fe III plus superparamagnetic Fe III . No Fe° species were detected, even under H 2 atmosphere.
