Abstract

Herein, we reported on developing facile synthetic route for reusable nanocatalysts based on combination of the supermagnetic properties of magnetite with unique optical and catalytic properties of noble metal hybrid nanomaterials. Comparing two different synthetic methods which is the best from the synthetic and applicable sides for synthesis of Fe3O4 and Fe3O4@M M=Ag or Au) core-shell hybrid nanostructures. The two different comparative single-step synthetic methods were: thermal decomposition and hydrothermal The structural, morphological and magnetic properties of the obtained Fe3O4 and Fe3O4@M nanoparticles were characterized by various techniques. XRD of the Fe3O4 nanoparticles exhibited sharp and strong diffraction peaks confirming the highly crystalline structure of the Fe3O4 particles synthesized by the hydrothermal method but broad and weak peaks on using thermal decomposition method. Both Fe3O4@Ag and Fe3O4@Au obtained by the hydrothermal method showed the reflection planes of Fe3O4 and additional planes of silver or Au.
