Abstract
In this work, we reporta simple and green approach method for the green synthesis of stable silver
nano particles (AgNPs) using syzigium cumini leaf extract. Leaf extract acts as both reducing and stabilizing agent.
The synthesized nanoparticles were characterized using UV-visible spectroscopy (UV-vis), Fourier transform
electron microscopy(FTIR), X-ray powder diffraction (XRD), Scanning electron microscopy(SEM), zeta Potential
and Transmission electron microscopy (TEM).The synthesized AgNPs was characterized by a peak of 439-
441nm.The influence of reaction time on the synthesis of nanoparticles were studied. Zeta potential value -14.1shows
a moderate stable of silver nanoparticles with Syzigium cumini leaf extract. The TEM image clearly shows the
synthesized silver nanoparticles shape is spherical and the average size is 13 nm. Synthesized nanoparticles had
significant anti-bacterial activity and it also shows good catalytic activity on the reduction of para nitro phenol (4-
NP) to para amino phenol (4-AP).
