Sažetak
Magnetic nanomaterials have been getting a lot of attention lately due to their specific physical properties and various applications in medicine and biomedicine as well as support for photocatalyst in advanced oxidation processes for degradation of organic micropollutants. Magnetic behaviour of nanomaterials greatly depends on their particle size. Such behaviour enables a facile extraction of the magnetic nanoparticles from matrix or solution using an external magnetic field. In this paper, magnetic nanoparticles were successfully prepared via rapid microwave- assisted synthesis. They were subsequently coated with a layer of silica (SiO2) as a protective layer for magnetite and after that with titania (TiO2) to photocatalytically degrade micropollutants from wastewater. The prepared nanocomposites were characterized by Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), on behalf of which the core-shell configuration and chemical distribution of iron oxide, silica and titania chemical species was discussed.
