Abstract

The synthesized magnesium ferrite-titania-zinc oxide nanocomposites are extremely successful in the photocatalytic degradation of eosin Y dye because of their size, stability, structure, eco-friendliness and high efficiency. The UV-visible, XRD, SEM, TEM, FTIR and VSM techniques were used to analyze the structure of the nanocomposites. The value of band gap energy for nanocomposite is 2.3 eV. The synthesized nanocomposites were investigated for their efficiency in degrading eosin Y dye under visible light, with studies conducted at different time intervals and evaluation of catalyst reusability. The obtained nanocomposites exhibit an extensive surface area, which facilitates numerous active sites for interactions between the dye molecules and the metal oxide nanoparticles when exposed to visible light. The antibacterial activity of the prepared nanocomposites were also conducted against Gram-negative Aeromonas and Gram-positive Firmicutes and the results have shown very efficient antibacterial activity.
