Synthesis and Characterization of Silver Nanoparticles Using Celastrus Paniculatus Leaf Extract
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
This paper reports a rapid and ecofriendly green method for the synthesis of silver nanoparticles from silver nitrate solution using Celastrus Paniculatus leaf extract. Effect of Celastrus Paniculatus leaf extract , silver nitrate concentration, reaction time and temperature on reaction rate were investigated. The synthesized silver nanoparticles(AgNPs) were characterized with X-Ray diffraction (XRD), Fourier Transform Infrared spectroscopy(FTIR), Scanning Elctron microscopy (SEM) and Energy Dispersive X-ray analysis (EDX) and UV-Vis spectrscopy. All these results indicate the formation of silver nanoparticles and the gave surface plasmon resonance SPR) at 437 nm reveals the reduction of silver ions (Ag+) to silver (Ag0) which indicates the formation of silver nanoparticles (AgNPs) . The nanoparticles synthesised in this route were spherical in shape and were around 29 to 57 nm in shape as observed by Scanning Electron Microscopy (SEM).
