Abstract

Silver/ silver chloride (Ag/AgCl-NPs) nanoparticles were synthesized by a simple procedure using Albizia julibrissin flowers extract. The flowers of Albizia julibrissin extract acts a reducing, chlorinated and capping agent in the formation of Ag/AgCl-NPs. UV-visible spectroscopy was used to monitor the quantitative formation of silver/ silver chloride nanoparticles. For complete conversion of silver ions to silver/ silver chloride nanoparticles, time of reaction is less than 5 min at temperature 80oC and 24h in dark conditions at room temperature. The synthesized Ag/AgCl-NPs nanoparticles were characterized with X-ray diffraction (XRD), UV-vis Spectroscopy, scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FT-IR). UV-visible absorption studies revealed surface plasmon resonance (SPR) peak around 410-430 nm, confirming the presence of Ag/AgCl nanoparticles. The average particle size ranged from 5-20 nm. The particle size could be controlled by changing the flowers extract, silver ion concentration and temperature. FT-IR spectra of flowers extract before and after the synthesis of silver/ silver chloride nanoparticles were determined to allow identification of possible functional groups responsible for the reduction of silver ions to silver/silver chloride nanoparticles.
