Catalytic Reduction of P-Nitro Phenolusing Green Synthesized Silver Nanoparticles and their Anti-Bacterial Activity. International Journal of Applied Biology and Pharmaceutical Technology. 2015 Oct-Dec; 6(4): 20-28.0976-4550http://imsear.searo.who.int/handle/123456789/169093In 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).ensilver nanoparticlessyzigium cumini leaf extractcatalytic activityanti-bacterial activityArticle
