Synthesis and Characterization of Novel Fe3O4/PVA/Eggshell Hybrid Nanocomposite for Photodegradation and Antibacterial Activity

Abstract

In the 21st century, hybrid nanocomposites were widely used in bioelectronic, biosensing, photocatalytic, and biomedical applications. In the present study, we fabricated a novel Fe3O4/PVA/Eggshell hybrid nanocomposite and physicochemically characterized it using powder XRD, EDS, FTIR, VSM, and HR-TEM analysis. The XRD spectrum revealed the crystalline and FCC configuration of Fe3O4 NPs with average crystal size of 16.28 nm, and the HRTEM image indicates the prepared hybrid nanocomposite is of spherical shape with less agglomeration. This hybrid nanocomposite showed a significant photodegradation property in degrading organic pollutants such as congo red and crystal violet dyes under the sunlight irradiation. In addition, the hybrid nanocomposite also displayed a potent antibacterial property against different Gram +ve and Gram −ve bacterial pathogens. This study provides a significant example in the overview of fabrication of cost effectively, eco-friendly, and multiple-application hybrid nanocomposites through eggshell membrane fibers.

“…The vibration band, which was attributed to belonging to OH stretching at 3420 cm -1 in the literature was observed at 3444, 3445, and 3409 cm -1 in PC-Cu, PC-Pb, and PC-Al, respectively. On the other hand, this band was seen at 3422, 3387, 3332 and 3469 cm -1 in CPC-Cu, CPC-Pb, CPC-Ag and CPC-Al samples, respectively [32], [33]. Most of the characteristic peaks of eggshells were seen in calcined eggshells samples.…”

“…3(c)). However, it is noteworthy that all the peaks and bands are less intense for lower nanofiller content and become more intense with increasing nanofillers concentration, resulting from the bond formation between the polymer blend, GQDs and Fe 2 O 3 NPs [52,53]. (Fig.…”

Antibacterial Effect of Green Synthesized Silver Nanoparticles using Cineraria maritima

“…The anti-bactericidal activity of Cm-Ag NPs fabricated fabric sample was demonstrated in this study, which showed considerable growth inhibition properties against the test pathogen Different processes could be involved in the anti-bacterial properties of NPs such as the interaction of NPs on the surface of the bacteria cell membrane, ribosome disassembly, inactivation of essential enzymes, which are involved in the protein synthesis, NPs interact with cell signaling, etc. Nevertheless, the antibacterial effects of NPs are mostly determined by the size, shape, and kind of capping agent present on the NP's surface (Francis et al 2020;Gupta et al 2021). In the present study, the prepared Cm-Ag NPs coated fabric sample demonstrated a significant anti-bacterial effect on E. coli, the zone of inhibition was 18 mm, whereas, the uncoated fabric sample had no inhibition zone and hence it can be used to treat and manage a wide range of microbial infections.…”
