Green Synthesis and Characterization of Silver Nanoparticles using Piper Betel Leaf Extract

Green synthesis of nanoparticles by biological reduction method using plant extract is recent development in synthetic chemistry. The green method of nanoparticles is easy, efficient and eco-friendly on comparison with other methods. Silver nanoparticles are synthesized by biological reduction of silver nitrate. Betle leaf extract was used to reduce the silver salt in to its silver nanoparticles. As prepared silver nanoparticles sample was characterized for its structure by employing powder X-ray diffraction (XRD) tool. The morphology of said metal nanoparticle was studied by Scanning Electron Micrograph (SEM) tool. Fourier Transform infrared (FTIR) spectral study was undertaken to know the bonding in the prepared silver sample. Formation of Ag particles was confirmed by energy dispersive X-ray analysis (EDX) study.Key words: Green synthesis, nanoparticle, Betle leaf extract, XRD, SEM, FTIR, EDX* Author for correspondence: Â arun_lagashetty@yahoo.co
