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.

Summary
Environmental decontamination by photocatalysis is of great interest to the researchers worldwide for its effective conspicuous process [1]. Among various metal oxide nanoparticles (NPs), the Fe3 O4 NPs are found to be an ideal photocatalyst for their high magnetization, high coercivity, superior photon-absorbing capacity, and strong bonds between the molecules due to the better dipole–dipole interactions [4]. These nanostructures show a high degree of agglomeration after synthesis, the polymer coating on their surface provides excellent stability. Several natural and synthetic polymers have been reported for the development of NPs/polymer nanocomposites [5] Among these polymers, polyvinyl alcohol (PVA), a water-soluble polymer, subsequently prevents the agglomeration of NPs resulting in their mono-dispersed condition and prevents the NP’s oxidation [6]. In order to improve the photocatalytic activity against organic pollutants such as dyes, the addition of eggshell components with NPs has been used as an effective dye adsorbent from the aqueous solution
