Microwave-Assisted Synthesis Core-Fe3O4 Shell-Au Cubic Nanoparticles

الملخص EN

Core-Shell (Fe3O4/Au) nanoparticles were synthesized using iron II chloride tetrahydrate (FeCl2H2O) and potassium tetrachloroaurate III (AuCl4K) precursors under microwave-assisted conditions.

Products were analyzed using field emission gun electron microscope in transmission and scanning modes; energy disperse X-ray spectroscopy performed during STEM measurements indicated a signal for gold K and M signals at 9 keV and 13 keV, respectively, confirming Au atoms at nanoparticle's perimeter and Fe-L signal at 8 keV to be at the center.
