Nanocomposites of monodisperse nanoparticles embedded in high-K oxide matrices ? a general preparation strategy

Original language description

We present a general approach, which enables preparation of multifunctional nanocomposites of monodisperse nanoparticles embedded in oxide matrices. The two-step route has been successfully applied to nanocomposites composed of CoFe2O4 nanoparticles embedded in high-K oxide matrices (ZrO2, Al2O3, TiO2). First, hydrophobic CoFe2O4 nanoparticles were produced by hydrothermal synthesis and then their incorporation in the oxide matrix was completed by the sol?gel method using the corresponding alcoxides. The as-prepared samples were annealed at temperatures ranging from 200 to 700 °C and characterized in detail by several methods. The particle size does not change with the annealing temperature, while the amorphous matrices crystallize at temperatures above 400 °C. At higher annealing temperatures, partial decomposition of the CoFe2O4 occurs. The proposed method allows preparation of nanocomposites constituted of uniform nanoparticles embedded in the favored oxide matrix.
