What is Fe3O4?
Fe3O4 nanoparticles have unique properties, including magnetic properties, large surface area, and low toxicity. Natural iron sand is a natural resource that has iron oxide compounds. Then, we will highlight the use of Fe3O4-based NPs in emerging applications, such as biomedical applications (hyperthermia, MRI contrast agents, and drug delivery), biosensing, environmental applications for removing heavy metals and organic pollutants, and energy storage devices. The one-step reaction, i.e., Fe3O4→FeO, and the two-step reaction, i.e., Fe3O4→FeO→Fe, occurred before and after the transformation point. Fe3O4 was synthesized by the coprecipitation method using FeCl3. 6H2O and (NH4)2Fe(SO4)2. 6H2O precursors dissolved in distilled water in a mol ratio of Fe3+: Fe2+ = 2:1. NaOH solution was added slowly into the iron solution with continuous stirring for 60 minutes in an Argon gas atmosphere. In neutral suspensions (R<1), Fe3O4 is formed via green rust II or a mixture of green rust II and Fe(OH)2. By further oxidation, the Fe3O4 formed gradually changes to γ-Fe2O3.
How do you disperse Fe3O4?
No dispersing agent is needed – only 30-40 minutes by using a piece of high-speed mixture equipment to obtain very stable water dispersion, and the stable Fe3O4 water dispersion can be further diluted into low concentration Fe3O4 stable water dispersion – To further dilute it to your desired concentration—rust from Iron (III) oxides with limited oxygen. Black rust can be visually identified as a thin, black film resulting from oxidation in a low-oxygen environment. Black rust has an appearance of almost a black stain. A synthesis of the Fe3O4 particle as a ferrofluid filler with surfactant oleic acid dispersed in olive oil has successfully been performed. The magnetic nanoparticle has a particle size of 8.8 nm sized particles. The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic, and that among octahedral ions is ferromagnetic; overall, a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB). FeO is the most basic because …it easily ionizes as a base in an aqueous solution than others.
Is Fe3O4 soluble in water?
The Fe3O4 NPs are quite stable and can be freely dispersed in water. The as-prepared magnetic nanoparticle solution can be stable for more than one month. The mean diameter of the Fe3O4 NPs can be controlled in the range of ∼20 to ∼40 nm in mean diameter. In summary, Fe3O4 is formed through iron oxidation, iron oxide reduction, and the combination of iron oxide and iron. This process can occur naturally or be achieved through industrial processes. Fe3O4 was synthesized by the coprecipitation method using FeCl3. 6H2O and (NH4)2Fe(SO4)2. 6H2O precursors dissolved in distilled water in a mol ratio of Fe3+: Fe2+ = 2:1. NaOH solution was added slowly into the iron solution with continuous stirring for 60 minutes in an Argon gas atmosphere. Magnetite (or Fe3O4) is an elaborate rust – a regular oxygen and iron atoms lattice.
