The possibility of using Ti(III) complexes to produce metals of the iron subgroup in aqueous solution at room temperature has been studied. The influence of the solution composition and of the deposition conditions on the process of the reaction has been investigated. The metal reduction was shown to be accompanied by hydrogen generation via the reaction of water reduction with Ti(III) complexes, which is catalyzed with the metal particles formed. The metal powders produced were investigated by X-ray diffraction and transmission electron microscopy methods. The peculiar feature of the reductant used, when compared to conventional hydrogen-containing ones, is that upon employing it ultrafine (10-30 nm) particles of pure polycrystalline highly monodisperse nickel, cobalt, and iron powders are produced, which form chain structures.
