Durian Peeling Extract Mediated Green Synthesis of Silver Nanoparticles

Abstract

In this work, silver nanoparticles (AgNPs) were successfully synthesized from AgNO₃ through a simple and eco-friendly method, also called the green synthesis, using Mon Thong durian (Durio zibethinus L.) peeling extract. The main role in synthesis mechanism of AgNPs is using polysaccharides in durian rind as a reducing agent as well as stabilizer. The appearance of a yellowish-brown color in mixture of AgNO₃ solution and durian rind extract is the indication of formation of AgNPs. The synthesized AgNPs were characterized by UV-visible spectroscopy, transmission electron microscopy (TEM) and X-ray diffraction (XRD) spectrometry. The AgNPs were found to be polycrystalline in nature and spherical particles with diameter of 11.7 ± 3.2 nm. The crystallinity with fcc phase is evidenced by clear lattice fringes in SAED pattern and diffraction peaks in the XRD pattern corresponding to the (111), (200), (220), and (311) planes.
