The Ni-nanoparticles, being similar to the nanocores of the Ni/Au core–shell nanoparticles, are made up of the structural domains with the dimensions about 1 nm. It is experimentally shown in this work for the first time by the combination of the small-angle X-ray scattering (SAXS) and the powder X-ray diffraction (XRD). The atomic structure of these domains is not a face-centered cubic lattice (FCC) inherent in the bulk state of Ni. This fact has been established by using the transmission electron microscopy (TEM) and XRD, calculated and confirmed by the observed features of an anodic oxidation and the differential scanning calorimetry (DSC) results for the investigated Ni-nanoparticles. Thus, the Ni-nanocores are composed of the domains with a structure formed by the icosahedra in the synthesis often used to obtain the core–shell nanoparticles.
