Aging of Iron Nanoparticles in Aqueous Solution: Effects on Structure and Reactivity
Abstract
Aging (or longevity) is one of the most important and potentially limiting factors in the use of nano-Fe 0 to reduce groundwater contaminants. We investigated the aging of Fe H2 (Toda RNIP-10DS) in water with a focus on changes in (i) the composition and structure of the particles (by XRD, TEM, XPS, and bulk Fe 0 content) and (ii) the reactivity of the particles (by carbon tetrachloride reaction kinetics, electrochemical corrosion potentials, and H 2 production rates). Our results show that Fe H2 becomes more reactive between 0 and ∼2 days exposure to water and then gradually loses reactivity over the next few hundred days. These changes in reactivity correlate with evidence for rapid destruction of the original Fe(III) oxide film on Fe H2 during immersion and the subsequent formation of a new passivating mixed-valence Fe(II)−Fe(III) oxide shell. The effect of aging on the rate of carbon tetrachloride reduction was best described by the corrosion potential of Fe H2, whereas the yield of chloroform from this reaction correlated best with the rate of H 2 production. The behavior of unaged nano-Fe 0 in the laboratory may be similar to that in field-scale applications for source-zone treatment due to the short reaction times involved. Long-term aged Fe H2 acquires properties that are relatively stable over weeks or even months.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
