Degradation and removal of organic pollutants by BaFe2O4 nanostructures, synthesis and characterization

BaFe2O4 nanostructures have been synthesized through a simple sonochemical reduction approach. X-ray diffraction characterization suggested that the product consists of cubic phase pure BaFe2O4. The as-prepared products were also characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). An X-ray energy dispersive spectroscopy (EDX) study further confirmed the composition and purity of the product. The synthesis procedure is simple and uses less toxic reagents than the previously reported methods. Other factors, such as the reaction time, temperature, different capping agent and the reductant type also have an influence on the morphology of the final products to some extent. The photocatalytic activity of the synthesized products has been compared for degradation and removal of organic pollutants.
