Abstract
Strontium hexaferrite nanocrystallites were prepared by the sol–gel autocombustion method followed by calcination at 900 °C for 1h under different molar ratios of reductant/oxidant. The structural properties of strontium hexaferrite nanoparticles were studied by X-ray diffraction XRD and scanning electron microscopy SEM. The results showed that the particle size of the resultant powder was about 50-80 nm. The photocatalytic activity of magnetic strontium hexaferrite under UV light was evaluated using Methylene blue MB as a model compound for organic contaminants. The maximum degradation efficiency 46 was achieved at molar ratio of reductant/oxidizer 0.8. Reasonably high values of magnetization, the strontium hexaferrite nanoparticles could be easily separated from the environment by using a low strength magnetic field after the reaction.
