Microstructure of Iron (Fe) Nanowires Synthesized by Chemical Reduction of Different Fe Ionic Precursors

Iron (Fe)-based nanostructures are attractive applications in the areas of drug delivery, data/energy storage, catalysis due to their inexpensive price, biocompatibility and low-toxicity. The one-dimension (1D) Fe nanowires (NWs) assembled by isotropic Fe nanoparticles (NPs) with high values of anisotropy and magnetization have applications in magnetic transitions and electronic transmission due to its larger surface-to-volume ratio However, in addition to the challenge of fabricating Fe chain-like NWs without templates, few microstructure study of Fe nanowire with different valence state can be found. This research investigate the microstructure difference between Fe(II) and Fe(III) using HRTEM, electron diffraction and electron energy loss spectroscopy (EELS).
