Synthesis and Characterization of Fe and Ag Core/Shell Nanoparticles

Abstract

This paper presents current results of the synthesis and characterization of Ag/Fe and Fe/Ag core/shell nanoparticles, as well as the future applications of these materials. By manipulating the introduction time of Silver Nitrate into a solution of Sodium Borohydride, Trisodium Citrate, and Iron (II) Sulfate we were able to demonstrate the control of the material that forms the core and shell of the nanomaterial. Different introduction times of Silver Nitrate have yielded different material configurations (Ag/Fe vs Fe/Ag - core/shell).
