Iron oxide are a group of compounds made up of iron and oxygen linked together by chemical bonds. The rust you see on metal is an example of natural iron oxide formation. Rust forms when iron is exposed to oxygen and water, and a chemical reaction called oxidations occurs. During the rusting process, iron atoms bond with oxygen atoms to create Iron oxide that are typically red, brown or orange in color. Water is necessary for Iron oxide to form, either in the form of water or moisture from the air. Most Iron oxide are now produced synthetically under more controlled circumstances since naturally oxidized iron can contain impurities like heavy metals that aren't desirable and may be harmful.

Iron oxide abound in nature where they serve a variety of biological functions. In addition, they're used as an ingredient in household and personal care products. One way they're commonly used is to make paint pigments used by artists. They're also used to dye concrete, tiles, rubber and leather. Iron oxide form deep yellow or orange shades and various shades of red and brown, so they're ideal for creating earth-tone paints and pigments. There are also black oxides that are deep black in color. Iron oxide have been used as paint pigments since very early times to create earthy colors like umber and sienna that artistic people can use to paint realistic landscape paintings.

Iron oxide is also used in the manufacture of electronic parts and magnets and to create the magnetic strip on the back of credit cards and ATM cards. In addition, they're used in the pharmaceutical industry to add color to tablets and capsules. More recently, iron oxide nanoparticles have been used to deliver drugs and medications to specific areas of the body.

Another area were Iron oxide are useful is in the cosmetic and personal care industry, Because Iron oxide come in shades or red, orange, brown and black, cosmetic manufacturers use them to add color to cosmetic products like eye shadow, blush, face powders, lipstick and mineral makeup. Using Iron oxide as coloring agents in cosmetics has some advantages. They're resistant to moisture, don't easily bleed or smear and have "staying power" so you don't have to keep reapplying your eye shadow or blush. They also create intense pigments that have a rich color.

Iron oxide pigments work well in makeup products that remain on the surface of the skin, but they aren't ideal for permanent makeup placed beneath the skin. When they're placed into the dermis of the skin during the application of permanent makeup, the iron is gradually absorbed by blood vessels in the dermis, and the color can change or fade. Therefore, iron oxide pigments aren't truly permanent when injected subcutaneously.

Iron oxide are found in a wide array of cosmetic products from eye shadow to talcum powder - even products that are marketed as natural or organic. That's because they're safe, although the iron oxide in cosmetics is made synthetically. Iron oxide are made in a lab for safety reasons since naturally produced varieties often contain impurities. These impurities aren't an issue when Iron oxide are made under carefully controlled conditions. Cosmetic-grade Iron oxide are made from mined iron salts that are then oxidized in a laboratory and purified. Oxides formed in a natural, uncontrolled setting are often contaminated with heavy metals like arsenic, mercury and cadmium. This is an example of natural not always being safer.

Iron oxide are gentle and non-toxic in cosmetic products placed on the surface of the skin, although they aren't suitable for permanent cosmetics placed into the dermal layer of the skin since they can be absorbed by blood vessels and lead to color changes. They're usually not irritating to the skin and aren't known to allergenic. The few reports of allergic reactions to Iron oxide have turned out to be an allergy to nickel instead. Iron oxide typically don't cause problems even for people with sensitive skin. All in all, they're safe and non-irritating in the amounts found in cosmetic products.

Iron oxide surfaces

The current status of knowledge regarding the surfaces of the iron oxides, magnetite (Fe3O4), maghemite (污-Fe2O3), haematite (汐-Fe2O3), and w邦stite (Fe1−xO) is reviewed. The paper starts with a summary of applications where iron oxide surfaces play a major role, including corrosion, catalysis, spintronics, magnetic nanoparticles (MNPs), biomedicine, photoelectrochemical water splitting and groundwater remediation. The bulk structure and properties are then briefly presented; each compound is based on a close-packed anion lattice, with a different distribution and oxidation state of the Fe cations in interstitial sites. The bulk defect chemistry is dominated by cation vacancies and interstitials (not oxygen vacancies) and this provides the context to understand iron oxide surfaces, which represent the front line in reduction and oxidation processes. Fe diffuses in and out from the bulk in response to the O2 chemical potential, forming sometimes complex intermediate phases at the surface. For example, 汐-Fe2O3 adopts Fe3O4-like surfaces in reducing conditions, and Fe3O4 adopts Fe1−xO-like structures in further reducing conditions still. It is argued that known bulk defect structures are an excellent starting point in building models for iron oxide surfaces.

The atomic-scale structure of the low-index surfaces of iron oxides is the major focus of this review. Fe3O4 is the most studied iron oxide in surface science, primarily because its stability range corresponds nicely to the ultra-high vacuum environment. It is also an electrical conductor, which makes it straightforward to study with the most commonly used surface science methods such as photoemission spectroscopies (XPS, UPS) and scanning tunneling microscopy (STM). The impact of the surfaces on the measurement of bulk properties such as magnetism, the Verwey transition and the (predicted) half-metallicity is discussed.

The best understood iron oxide surface at present is probably Fe3O4(100); the structure is known with a high degree of precision and the major defects and properties are well characterised. A major factor in this is that a termination at the Feoct每O plane can be reproducibly prepared by a variety of methods, as long as the surface is annealed in 10−7−10−5 mbar O2 in the final stage of preparation. Such straightforward preparation of a monophase termination is generally not the case for iron oxide surfaces. All available evidence suggests the oft-studied (﹟2℅﹟2)R45∼ reconstruction results from a rearrangement of the cation lattice in the outermost unit cell in which two octahedral cations are replaced by one tetrahedral interstitial, a motif conceptually similar to well-known Koch每Cohen defects in Fe1−xO. The cation deficiency results in Fe11O16 stoichiometry, which is in line with the chemical potential in ultra-high vacuum (UHV), which is close to the border between the Fe3O4 and Fe2O3 phases. The Fe3O4(111) surface is also much studied, but two different surface terminations exist close in energy and can coexist, which makes sample preparation and data interpretation somewhat tricky. Both the Fe3O4(100) and Fe3O4(111) surfaces exhibit Fe-rich terminations as the sample selvedge becomes reduced. The Fe3O4(110) surface forms a one-dimensional (1℅3) reconstruction linked to nanofaceting, which exposes the more stable Fe3O4(111) surface. 汐-Fe2O3(0001) is the most studied haematite surface, but difficulties preparing stoichiometric surfaces under UHV conditions have hampered a definitive determination of the structure. There is evidence for at least three terminations: a bulk-like termination at the oxygen plane, a termination with half of the cation layer, and a termination with ferryl groups. When the surface is reduced the so-called ※bi-phase§ structure is formed, which eventually transforms to a Fe3O4(111)-like termination. The structure of the bi-phase surface is controversial; a largely accepted model of coexisting Fe1−xO and 汐-Fe2O3(0001) islands was recently challenged and a new structure based on a thin film of Fe3O4(111) on 汐-Fe2O3(0001) was proposed. The merits of the competing models are discussed. The 汐-Fe2O3(11‘02) ※R-cut§ surface is recommended as an excellent prospect for future study given its apparent ease of preparation and its prevalence in nanomaterial.

In the latter sections the literature regarding adsorption on iron oxides is reviewed. First, the adsorption of molecules (H2, H2O, CO, CO2, O2, HCOOH, CH3OH, CCl4, CH3I, C6H6, SO2, H2S, ethylbenzene, styrene, and Alq3) is discussed, and an attempt is made to relate this information to the reactions in which iron oxides are utilized as a catalyst (water每gas shift, Fischer每Tropsch, dehydrogenation of ethylbenzene to styrene) or catalyst supports (CO oxidation). The known interactions of iron oxide surfaces with metals are described, and it is shown that the behaviour is determined by whether the metal forms a stable ternary phase with the iron oxide. Those that do not, (e.g. Au, Pt, Ag, Pd) prefer to form three-dimensional particles, while the remainder (Ni, Co, Mn, Cr, V, Cu, Ti, Zr, Sn, Li, K, Na, Ca, Rb, Cs, Mg, Ca) incorporate within the oxide lattice. The incorporation temperature scales with the heat of formation of the most stable metal oxide. A particular effort is made to underline the mechanisms responsible for the extraordinary thermal stability of isolated metal adatoms on Fe3O4 surfaces, and the potential application of this model system to understand single atom catalysis and sub-nano cluster catalysis is discussed. The review ends with a brief summary, and a perspective is offered including exciting lines of future research.
