Recent Advances in the Applications of Hybrid Magnetic Nanomaterials as Magnetically Retrievable Nanocatalysts

Magnetic nanoparticles derived from iron oxide, for example, magnetite (Fe3O4) and maghemite (γ-Fe2O3), fulfill most of these requirements, and recent advances in their synthesis give access to size-controlled monodisperse particles. Hybrid magnetic materials have been synthesized from organic compounds and metal or metal oxide nanoparticles and examined as catalysts for the organic synthesis. When the reaction has been completed, the catalysts can be easily separated by simple external magnetic decantation.
