Mössbauer spectroscopy, X-ray powder diffraction, and transmission electron microscopy were used to study the reactions of Fe3O4 or FeCl2·4H2O nanoparticles stabilized in a polyethylene (HPPE) matrix with gaseous chlorine and hydrogen chloride. These reactions produce FeCl2·2H2O nanoparticles, which retain the particle size and distribution over the HPPE matrix intrinsic to precursor nanoparticles. We propose chemical modification of iron-containing nanomaterials as a means for manufacturing iron(II) chloride nanoparticles.
The synthesis and study of various nanomaterials and their properties have recently become a focus of research due to their unique electronic, optical, magnetic, and other physical and chemical properties. The physical and chemical properties of nanomaterials are primarily determined by their chemical composition. Therefore, preparing materials containing nanoparticles of the desired chemical composition is a problem faced by researchers. A considerable number of processes are known to yield metal-containing nanoparticles: chemical, electrochemical, pyrolytic, spark, micellar, and mechanochemical .
