14. Green synthesis of Nyctanthes arbor-tristisflower-decorated gold nanoparticles: Sustainable approaches for enhancing antimicrobial and supercapacitor performance

Author

Abstract

The physiochemical and electrochemical characteristics of gold nanoparticles (AuNPs) produced by phytosynthesis technique at varying concentrations of Nyctanthes arbor-tristisflower (NAF) are presented in this study. The final porous carbon decorated AuNPs have possible applications in antibacterial research as well as energy storage field. Transmission electron microscopy (TEM) studies revealed tiny spherical shaped nanoparticles, and UV–visible spectroscopy showed size-dependent optical properties. Significant antibacterial efficacy against Pseudomonas aeruginosawas shown by the NAF-derived AuNPs. A symmetric supercapacitor with 64 F g−1specific capacitance at 1 A g−1and 97% cycling stability after 5000 charge-discharge cycles was produced using the as-synthesized electrode. This study provides a sustainable method for producing multifunctional nanomaterials by highlighting the potential of NAF-derived AuNPs for dual applications in the antibacterial and supercapacitor areas.

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. This has useful applications, such as the creation of potential antibacterial compositions. The photocatalytic degradation of Congo red by prepared silver particles was studied under 150 min of UV light radiation. The produced silver nanoparticles' structural, optical, morphological, compositional, and bactericidal activity are all shown to be dependent on the concentration of HCS extract that is attached to the silver surface.
