Green Synthesis of Silver Nanoparticles Mediated using Lagerstroemia Speciosa and Photocatalytic Activity Against Azo Dye

Abstract

The present paper reports that the method is simple in the biosynthesis of silver nanoparticles using the aqueous leaves of L. speciosa. The functional groups for the plant extract and silver ions were explained by FTIR. The biosynthesized silver nanoparticles were characterized by UV-VIS spectroscopy, X-Ray Diffraction-XRD, High Resolution-Transmission Electron Microscopy, Zeta potential and particle size analysis. The maximum absorbance peak was found at 427 nm. The average silver nanoparticles were found to be 12 nm by XRD and it was spherical in shape. The nanoparticles were subjected to dye degradation process for methyl orange. Hence the biosynthesis silver nanoparticles possess photocatalytic. This evident helps to analysis the silver nanoparticles for various applications in future.
