Abstract

The present study explores that the aqueous extract of the seeds of Nyctanthes arbor-tristis (aka night jasmine) is very efficient for the synthesis of stable AgNPs from aqueous solution of AgNO3. The extract acts as both reducing (from Ag+ to Ag0) and capping agent in the aqueous phase. The constituents in extract are mainly biomolecules like carbohydrates and phenolic compounds, which are responsible for the preparation of stable AgNPs within 20 min of reaction time at 25 °C using without any severe conditions. The synthesized silver nanoparticles were characterized with UV–Visible spectroscopy, FT-IR, XRD and SEM. UV–Vis spectroscopy analysis showed peak at 420 nm, which corresponds to the surface plasmon resonance of AgNPs. XRD results showed peaks at (111), (200), (220), which confirmed the presence of AgNPs with face-centered cubic structure. The uniform spherical nature of the AgNPs and size (between 50 and 80 nm) were further confirmed by SEM analysis.

Highlights

The development of nanoparticle synthesis have got a remarkable recognition at present scenario because of the excellent implication of optical, chemical and biological properties

Summary

Introduction

The development of nanoparticle synthesis have got a remarkable recognition at present scenario because of the excellent implication of optical, chemical and biological properties. Various chemicals and physical methodology are listed for the synthesis of nanoparticles such as chemical reduction (Kholoud et al 2010), photochemical reduction (Kshirsagar et al 2014; Scaiano et al 2009), and electrochemical reduction (Roldan et al 2013; Yanga et al 2011). These processes sometimes depend on the toxic chemicals (such as solvent, reducing agent, capping agent) which may not be harmful for the synthesis of nanoparticles in industrial purposes but it is always expected to synthesize the
