AB  - Cobalt/magnesium ferrites with various mole percentage ratio of the metals (obtained structures are CoxMg1-xFe2O4 with x being 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1.0) were synthesized by sol-gel combustion synthesis using glycine as fuel, following the rules of propellant chemistry. The powders were then sintered at 700 °C for 3 hours. Obtained powders were characterized by X-Ray diffraction (XRD), scanning electron microscopy (SEM), Raman
spectroscopy, UV/vis diffuse reflectance spectroscopy (DRS). Investigation of the magnetic properties was also conducted by vibrating sample magnetometry (VSM). The obtained powders were proved to be phase-pure cubic spinels which formed agglomerated micrograins. Series of photocatalytic experiments of methylene blue degradation were done.
The influence of different experimental conditions was investigated including variations of: pH values, concentrations of the pollutant, masses of the photocatalyst, different light sources and therefore different light irradiation. Interesting results, including enhancement of the degradation rate with the introduction of cobalt into MgFe2O4 and decrease of the degradation rate with further increase of cobalt content and formation of hard agglomerates, open new possibilities for further investigation of the utilisation of Co/Mg ferrites as photocatalysts.

AB  - BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. Optimization of sintering conditions indicated that temperature of 800 °C and time of 2 h after pressing at 9 t/cm2 provided ceramics samples with the highest density (up to 96% of theoretical density) and the lowest content of secondary phases. Ferroelectric and magnetic characterization was performed on two selected ceramics samples with the highest densities. Ceramics obtained from the powder synthesized by the hydrothermal method showed greater lattice distortion along [1 1 1] axis and smaller grains, which resulted in larger values of electric polarization at room temperature. It also exhibited less Fe(3d)–O(2p) orbital overlapping due to a larger FeOFe bond angle, causing lower antiferromagnetic ordering and weak ferromagnetic behavior at low temperatures.
