Iron(III) Oxide - Structure, Properties, Uses of Fe2O3

Iron(III) oxide structure – Fe 2 O 3. The above image describes the structure of the Iron(III) oxide. Fe 2 O 3 is the chemical formula of Iron(III) oxide which has three oxygen atoms, two iron atoms. The oxidation state of Fe 2 O 3 is +3 and +2. The bond formation between oxygen and iron depends on the difference in electronegativity between these two atoms.

Geobacter metallireducens accesses insoluble Fe(III) …

Fe(III)-reducing microorganisms in the genus Shewanella have resolved this problem by releasing soluble quinones that can carry electrons from the cell surface to Fe(III) oxide that is at a distance from the cell. Here we report that another Fe(III)-reducer, Geobacter metallireducens, has an alternative strategy for accessing Fe(III) oxides.

Going Wireless: Fe(III) Oxide Reduction without Pili by ...

Previous studies have suggested that the conductive pili of Geobacter sulfurreducens are essential for extracellular electron transfer to Fe(III) oxides and for optimal long-range electron transport through current-producing biofilms. The KN400 strain of G. sulfurreducens reduces poorly crystalline Fe(III) oxide more rapidly than the more extensively studied DL-1 strain.

2020-8-31 · A few particles in the powders derived from 7.5 and 10 wt.% Fe 2 O 3 oxide compositions contained a third phase, determined by X-EDS to be intermetallic TiFe (Fig. 6d). These particles therefore must have originally had more Fe 2 O 3 locally and so contained enough Fe to retain the TiFe phase on completion of the reduction.
