Abstract

In the presence of Fe₃O₄ nano-fibers, we prepared SiO₂-Zn@Fe₂O₃ hybrid Nano-fibers through a novel and simple one-pot redox reaction between ZnSO₄ & SiO₂. The Fe₃O₄ exterior nano-fibers would be homogenously covered by SiO₂ coating to arrange a distinctive core-shell construction and then Zn nanoparticles are intercalated in the covering of SiO₂. The synthesized nanofibers were tested for photodegradation of methylene blue (MB). The result showed that 99 % MB was degraded in 60 min. Furthermore, the antibacterial potential of SiO₂-Zn@Fe₂O₃ nanofibers was tested against E. coli and S. aureus bacteria both in light and dark. The impact of different analysis such as Reactive oxygen species (ROS) analysis, irradiation effect on bacterial inhibition, concentration effect of SiO₂-Zn@Fe₂O₃ nanofibers and reduction of DPPH studied. The findings clearly demonstrate that ROS is produced in the presence of SiO₂-Zn@Fe₂O₃ nanofibers in bacterial cells and is responsible for their inhibition. Findings have shown that synthesized nanostructures can also increase the stability of DPPH radicals with increasing concentrations of nanomaterials, making them a strong candidate for DPPH reduction. The overall results show that the efficacy of SiO₂-Zn@Fe₂O₃ nanofibers for inhibition was more pronounced than that of individual iron oxides.
