Abstract

ABSTRACT: The synthesis of Fe3 O4 -Ag bimetallic nanoparticles by chemical reduction was carried out. Fe nanoparticles were obtained using Fe (III) Chloride hexahydrate (FeCl3 6H2 O) as precursor and sodium borohydride (NaBH4 ) as reducing agent, subsequently, a solution of silver nitrate (AgNO3 ) was added to the reaction. The synthesis methodology employed in this case, is a modification of chemical reduction method. Through this procedure has been possible simplify the synthesis route used to obtain bimetallic systems such as Fe3 O4 -Ag. Particles with semi-spherical morphology were observed. High-resolution transmission electron microscopy (HREM), ultraviolet visible spectroscopy (UV-is) and quasi-elastic light scattering (QELS) techniques were employed for the structural characterization of Fe3 O4 -Ag nanostructures. Some models presented describe and prove the formation of the Fe3 O4 -Ag alloy type structures.
