MgO Fe2O3 Core Shell Nanoparticles (Magnesium Oxide, 99.9%, APS: 80-100nm, Metal Oxide Core)

MgO Fe2O3 Core-Shell Nanoparticles

MgO Fe2O3 core-shell nanoparticles are composite nanomaterials consisting of a magnesium oxide (MgO) core with a thin layer of iron oxide (Fe₂O₃) as the shell. These core-shell nanoparticles leverage the unique properties of both components, combining the alkaline nature and high thermal stability of MgO with the magnetic, catalytic, and optical properties of Fe₂O₃.

The core-shell architecture not only allows for the enhanced performance of both materials but also provides significant control over the structure, size, and functionality of the nanoparticles. The MgO core contributes to mechanical strength, chemical stability, and the ability to modulate surface reactivity, while the Fe₂O₃ shell brings magnetic properties and catalytic activity that make these nanoparticles useful in a variety of technological and biomedical applications.
