Fabrication of PAN/Fe3O4 Nanofibers: Photocatalysis and Characterization Antimicrobial Properties
Mogomotsi N, Ranku,Omolola E, Fayemi, Elias E, Elemike
The present study aimed at green mediated synthesized iron oxides nanoparticles from peel extracts of pomegranate plant which is of immense medical, biological, and environmental value. The synthesized nanoparticles were characterized by using FT-IR, UV-Visible spectroscopy, SEM and TEM. FTIR revealed OH characteristic peaks at 3271 cm-1 and 1600 cm-1from the plant extract which serves as reducing agent for synthesis of Fe3O4 nanoparticles. SEM showed the morphology of Fe3O4 NPs. Photo catalysis studies reveal that Fe3O4/PAN Nano fibers andFe3O4nanoparticles showed increased efficiency towards the degradation of methylene-blue dye, which proof their potential application in waste water treatment. A synthesized Fe3O4 nanoparticle has degradation efficiency of 71.36 % and the Nano fibers exhibited efficiency of 22.68% towards methylene blue (MB) dye. However, further kinetic analysis of the degradation process put PAN/Fe3O4 Nano fibers at a better correlation coefficient of 0.9239 than the Fe3O4 nanoparticles. The green mediatedFe3O4NPs also exhibit an excellent antimicrobial activity against some selected pathogens conducted by disc diffusion method.
