6 Transition elements: the facts I 3. Catalytic properties Transition metals and their compounds can be: ● heterogeneous catalysts, for example: iron in the Haber process V2O5 in the Contact process ● homogeneous catalysts, for example: Mn2+ in the reaction between ethanedioate and manganate(VII) Fe2+ /Fe3+ in the reaction between iodide ions and peroxydisulphate (VI)
