Abstract:
In the present study, a bacterium resistance to heavy metals was isolated from contaminated areas. An eco-friendly and simple method was found to biosynthesis of silver nanoparticles (AgNPs) by reducing of aqueous Ag+ using the heavy metals resistance MKH1 bacterium. The biosynthesized AgNPs were characterized by UV-vis spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. A peak at about 420nm is related to absorption band of AgNPs which confirms by UV-vis spectroscopy. The SEM images showed that the biosynthesized AgNPs have mainly spherical shape with average diameters of 30-60nm. The electro-catalytic properties of AgNPs with different Ag content were investigated by different electrochemical tests. Biosynthesized AgNPs using isolated MKH1 show high catalytic activity and stability towards the oxidation reaction of hydrazine.
