In this study, nanometer sized of Ag/Fe3O4 nanocomposite (AFN) have been synthesized by using a simple and based on chemical reduction method. The size and shape of (AFN) controlled by using of condensation (Fe2O3 (2.975 mmol), NaBH4 (21.25 mmol), AgNO3 (2.532 mmol) and polyvinylpyrrolidone (PVP) (8.925 mmol K30 Mr=10.000) in 40 ºC. The synthesized AFN was characterized by XRD, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electron diffraction X-ray (EDX) spectral techniques. Measurements of X-ray diffraction (XRD) confirm that Ag/Fe3O4 nanocomposite have the crystalline structure. The scanning electron microscopy (SEM) images of the as-deposited Ag/Fe3O4 nanocomposite (AFN) have been shown that the particles aggregate into an organized spherical structure, which is characterized by 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 the average particle size for the AFN nanocomposite is 10-20 nm.
