Green Synthesis and Characterization of Silver Nanoparticles from Tectona grandis Leaf Extracts

Silver nanoparticles have garnered particular attention among the many noble metal nanoparticles because of their exceptional qualities, which include suitable electrical conductivity, chemical stability, catalytic activity, and antibacterial activity. Silver at the nanoscale has shown entirely different characteristics from bulk particles of the same material due to its high surface to volume ratio. This study, investigated the synthesis of green nanoparticles using extracts from Tectona grandis Leaf. The nanoparticles were characterized using UV-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometer (XRD), Scanning electron microscope (SEM) - Energy dispersive X-ray spectroscopy (EDX). Characterization studies indicated that Tectona grandis nanoparticles exhibited dark brown coloration with strong UV-visible absorption peaks at 420 nm. FTIR analysis confirmed the presence of hydroxyl, carbonyl, alkene, and amine functional groups. SEM microscopy revealed predominantly spherical or oval nanoparticle morphology. XRD analysis established the presence of silver with a defined crystalline structure. The Leaf extracts act as a reducing agent for nanoparticles synthesis, which consequently established the bioprocess with the advantage of being environmentally friendly.
