Molecular insights of oxidation process of iron nanoparticles: spectroscopic, magnetic and microscopic evidences

Oxidation behavior of nano-Fe0 particles in anoxic environment was determined using different state-of-the-art analytical approaches including high resolution transmission electron microscopy (HR-TEM) combined with energy-filtered transmission electron microscopy (EFTEM), X-ray absorption spectroscopy (XAS), and magnetic measurements. Oxidation in controlled experiments was compared in standard double distilled (DD) water, DD water spiked with tri-chloroethene (TCE) and TCE contaminated site water.
