One-Pot Synthesis of Ag/Fe3O4 Nanocomposite: Preparation and Characterization

In this study, Ag/Fe3O4 nanocomposite (AFN) was synthesized by using a simple chemical reduction based method. The size and shape of AFN was controlled by using condensation (Fe2O3 (2.975 mmol), NaBH4 (21.25 mmol), AgNO3 (2.532 mmol), and polyvinylpyrrolidone (PVP) (8.925 mmol K30 Mr=10.000)) at 40°C. The synthesized AFN was characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electron diffraction X-ray spectroscopy (EDS). The XRD Measurements confirmed that Ag/Fe3O4 nanocomposite has the crystalline structure. The SEM images of the as-deposited Ag/Fe3O4 nanocomposite (AFN) demonstrated that the particles aggregate into an organized spherical structure, which is characterized by a diameter of 10-20 nm. This type of porous aggregate is characterized by large surface area, which could have potential applications in the areas of catalysis and filtration. The population distribution as measured from the TEM images shows that the average particle size for AFN is 10-20 nm.
