Název v původním jazyce

Synthesis and characterization of Au-Ni nanoparticles

Popis výsledku v původním jazyce

AuNi nanoparticles (NPs) were prepared from HAuCl4 and acetylcetonate Ni(acac)2 by the solvothermal route of wet synthesis in oleylamine at 230°C. The hexane suspension and the dry nanopowder of the Au-Ni nanoparticles were prepared. Chemical compositionof as-synthesized AuNi NPs was obtained using inductively-coupled plasma-optical emission spectrometry (ICP-OES). The optical properties of nanoparticles were monitored using UV-Vis spectrophotometer. The hydrodynamic size of colloid nanoparticles was measured by dynamic light scattering (DLS). Size and shape of metal core of nanoparticles and morphology of aggregates were investigated by electron microscopy (SEM, TEM and HRTEM). Hydrodynamic size of AuNi NPs measured by DLS was compared with the metallic core size obtained by electron microscopy. The thermal properties of AuNi NPs were evaluated by differential scanning calorimetry (DSC) and temperature controlled X-ray diffraction method (t-XRD).
