| Popis: | This paper shows the possibility of nanoparticle preparation by precipitation in solid state and isolation by electrochemical dissolution of matrix. Two variants of nanoparticles were prepared by heat treatment of Cu–Fe supersaturated solid solution. The obtained nanoparticles with mean diameters of about 10 nm and 21 nm were examined by transmission electron microscopy and XRD analysis as core–shell nanoparticles, consisting of an α-Fe core and a 2-line ferrihydrite shell. |
