Environmentally friendly preparation of functionalized magnetite-silica (Fe3O4/SiO2) nanocomposites (NCs) with different SiO2 content (6, 20 and 50 wt%) using revised mechanosynthesis is reported. High-energy ball milling of alpha-Fe2O3, Si and SiO2 mixtures was followed by hydrolysis and condensation of 3-aminopropyl-triethoxysilane. X-ray powder diffraction and transmission electron microscopy showed the formation of almost spherical Fe3O4 nanocrystals with a narrow size distribution (4-6 nm) uniformly dispersed in the amorphous 100-200 nm SiO2 agglomerates. Scanning electron microscopy and energy dispersive spectroscopy were used to study the elemental distribution in the sample. Fourier transform infrared spectroscopy confirmed the NC surface functionalization with amino groups. Magnetic properties were also explored, indicating a homogeneous distribution of magnetic nanoparticles in the silica matrix.
