| Popis: | International audience; Amino-functionalized core–shell magnetic nanoparticles have been covalently grafted with Polyoxometalates (POMs). These multifunctional nanocomposites have been obtained through the coupling of heteropolytungstate-based hybrids bearing carboxylic acid functions with aminopropyl functions that decorate the core–shell nanoparticles. The physical properties of the resulting materials have been studied by a large set of techniques. The very good nanostructuration of the POMs at the surface of the obtained nanoparticles have thus been directly observed by high-resolution transmission electronic microscopy (HR-TEM). Furthermore, the hyperthermia properties of these nanocomposites have been also considered as a function of the size of the magnetic core. Finally, the stability of these suspensions in organic media makes them particularly interesting in the frame of their processing or their potential use as nanocatalysts. |
