Structural Effects of Iron Oxide Nanoparticles and Iron Ions on the Hydrothermal Carbonization of Starch and Rice Carbohydrates
Open accessAbstract
A carbohydrate diet: Free iron ions and Fe2O3 nanoparticles have been employed to direct the hydrothermal carbonization of starch and rice under mild conditions (≤200 °C). Well-defined carbon nanostructures with various forms (see figure) can be conveniently synthesized in gram-scale quantities from these highly abundant starting materials.

Metal ions such as iron ions could effectively accelerate the hydrothermal carbonization process, shortening reaction time to some hours.
“Cui et al. [37] reported that metal ions, such as iron ions, could effectively accelerate the hydrothermal carbonization process, which shortened the reaction time to some hours.”
From Preparation of Microporous Carbon from <i>Sargassum horneri</i> by Hydrothermal Carbonization and KOH Activation for CO<sub>2</sub> Capture (2018) · cites this paper as [37]
The main text says metal ions can accelerate hydrothermal carbonization of starch and reports that iron ions catalyze the process. The Experimental Section describes an iron-ion reaction lasting 12 hours, but our copy does not establish that iron ions shortened the reaction time to that duration compared with a reaction without them. (LLM, conf=0.86)
Experimental — accuracy not yet measuredIron ion can accelerate hydrothermal carbonization reaction and promote formation of pores.
“Secondly, iron ion can accelerate hydrothermal carbonization reaction and promote the formation of pores.”

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.
