Fabrication of biomass derived carbon supported iron oxide composites for antibacterial and antifungal activity

We examine the antibacterial and antifungal activity of the magnetic carbon aerogel composites (Fe3O4/C) were prepared by simple hydrothermal followed by the co-precipitation method. The carrot was used as a carbon source and FeSO4.7H2O and FeCl3.6H2O were used as a metal source. A similar synthetic procedure was used to prepare different Fe3O4/C nanostructured composites (45, 60 and 75 wt%) and for the comparison purpose, pure Fe3O4 nanoparticles were prepared without the addition of carbon. The preparation of Fe3O4/C composites has been confirmed by XRD, FTIR, FESEM and TEM analysis and their antibacterial and antifungal activity against Staphylococcus aureus-902 & Escherichia Coli-443 and Aspergillus Niger & Candida albicanshashas been studied. The synthesized Fe3O4/C composites are found to be extremely toxic against S. Aureus- 902 & E. Coli443 and A. Niger& C. Abicans. The newly fabricated Fe3O4/C composites could be effective antibacterial & antifungal properties, the corresponding synthetic approach used in various filed such as energy storage devices, adsorbent of removal of toxic dyes and heavy metals, and catalysis for the pharmaceutical field.

Automated summary

In this study, magnetic carbon aerogel composites were prepared by simple hydrothermal and co-precipitation methods, and their antibacterial and antifungal activity was investigated. The results showed that the synthesized composites exhibited significant inhibitory effects against various bacteria and fungi. Additionally, these composites also showed potential applications in energy storage devices, removal of toxic dyes and heavy metals, and catalysis in the pharmaceutical field.
