Hibiscus cannabinus seeds assisted spherical silver nanoparticles and its antibacterial and photocatalytic applications

Abstract

Green nanomaterial manufacture limits hazardous substances and encourages noxious-free environments. The fields of photocatalysis and antibacterial resistance are more promising because of their chemical reductants and sterile environments. Here, we used Hibiscus Cannabinus seed as a bio source and developed a simple, environmentally friendly approach for the biosynthesis of AgNPs. Researchers and scientists have recently shown a strong interest in the green synthesis of silver nanoparticles due to their ease, eco-friendliness, non-toxicity, low cost, and ability to function as an antibacterial agent. Research goals include producing environmentally friendly, bacteriocidal, and photocatalytic dye removal products that can be applied to biomedical and water reuse applications. In this paper, we have reported spherical-shaped silver nanoparticles synthesized from Hibiscus cannabinus seeds and their characterization by X-ray Diffraction method, UV-Visible Spectroscopy, and Transmission Electron Micrograph. The surface functionalization of prepared silver particles by phenolic compounds in Hibiscus cannabinus seeds enhances antibacterial activity. Both Staphylococcus aureus and Escherichia coli are inhibited by the prepared silver nanoparticles. By preparing silver nanoparticles at a significantly higher extract concentration, we were able to obtain effective and increased bactericidal activity. The photocatalytic degradation of congo red by prepared silver particles was studied under 150 min of UV light irradiation. The produced silver nanoparticles' structural, optical, morphological, compositional, and bactericidal activity are all shown to be dependent on the concentration of Hibiscus cannabinus seeds extract that is attached to the silver surface.
