Abstract
The iron-containing phases in fresh and partly deactivated vanadium oxide catalyst are identified by Mössbauer spectroscopy. As a result of exploitation of the catalyst the new phases of Fe3O4, FeSO4 and Fe2(SO4)3 alongwith presence of α-Fe2O3 are formed. The Mössbauer spectroscopy presents new possibilities for studying the composition changes in iron-containing phases, and provides a tool to reveal the reasons leading to deactivation of industrial vanadium catalysts.
