EFFECT OF THE CHEMICAL NATURE OF POLYOXOMETALATE COMPLEXES ON REDOX PROCESSES LEADING TO THE FORMATION OF METALLIC SILVER NANOPARTICLES

摘要

It was shown that the reaction of solid polyoxometalate compounds containing tetraamine cations of nickel(II) or copper(II) with an aqueous solution of silver(I) nitrate leads to the formation of nanoclusters of the metal with sizes of 6-10 nm, localized on the surface of the crystalline matrix. It was established that the realization of the oxidation-reduction processes depends substantially both on the cationic and on the anionic component of the polyoxometalate complexes.
