AI Article Synopsis
- The study presents a method for creating uniform iron carbide and iron/iron carbide nanoparticles that have strong magnetization and stability in air.
- The synthesis technique involves breaking down Fe(CO)(5) on iron seed particles, which allows for control over carbon diffusion and the manipulation of the magnetic characteristics of the nanoparticles.
- These nanoparticles exhibit exceptional hyperthermia properties, making them promising for use in medical treatments at moderate magnetic fields.
Article Abstract
We report a tunable organometallic synthesis of monodisperse iron carbide and core/shell iron/iron carbide nanoparticles displaying a high magnetization and good air-stability. This process based on the decomposition of Fe(CO)(5) on Fe(0) seeds allows the control of the amount of carbon diffused and therefore the tuning of nanoparticles magnetic anisotropy. This results in unprecedented hyperthermia properties at moderate magnetic fields, in the range of medical treatments.

Iron phthalocyanine (FePc) is a promising non-noble metal catalyst for oxygen reduction reaction (ORR). While, with the plane-symmetric FeN site, the ORR activity of FePc is generally low due to its low ability to adsorb and activate O. Herein, we anchor FePc on Mg(OH)/N-doped carbon nanosheets building the ternary plate-like catalyst FePc/Mg(OH)/NC.

Enormous amounts of toxic synthetic dyes and inorganic contaminants, such as heavy metals, are regularly discharged into local water bodies unregulated and untreated through effluents from a wide range of industries. Designing industrial methodologies that limit or eliminate the unloading of harmful substances in the surrounding environment has become a requisite for sustainable growth. Although the magnetic separation-based adsorption technique seems quite promising, the functional moieties on the nanoparticle surface often restrict the choice of target pollutants, limiting their universal applicability.
