Structural Characterization of Fe-Ag Bimetallic Nanoparticles Synthesized by Chemical Reduction

Aims: The main objective of this research is to establish an efficient route for obtaining dumbbell bimetallic nanoparticles. Likewise, correlating the results of structural characterization with the particles synthesis conditions.

Methodology: Fe nanoparticles were obtained using Fe (III) Chloride hexahydrate (FeCl3·6H2O) as precursor and sodium borohydride (NaBH4) as reducing agent, subsequently, a solution of silver nitrate (AgNO3) was added to their action.

Results: Bimetallic particles were obtained in an aqueous medium and were later studied using the technique of high-resolution transmission electron microscopy (HREM), ultraviolet visible spectroscopy (UV-is) and quasi-elastic light scattering (QELS).

Conclusion: Particles with semi-spherical morphology were observed, likewise, a particle size distribution of 20nmwas recorded for the particles of Fe and 7nmin the case of Ag additionally inter planar distances corresponding to oxides of Fe were found.
