Abstract

In this study, we report the synthesis of silver nanoparticles (AgNPs) by using a simple green synthesis method. 30 nm sized AgNPs prepared by using tea extract and Ag salt at normal room temperature. The AgNPs synthesized via this one-pot greener approach, can be used as a promising material in different fields such as cosmetics, foods, medicine and pollutant degradation, etc. This environment benign did not use of any extra capping or reducing agent or template. As synthesized nanoparticles were evidenced by advance analysis techniques such as: UV-Vis spectroscopy, transmission electron microscopy (TEM), powder X-ray diffraction (PXRD) and fourier transform infrared (FTIR) spectroscopy, etc. X-ray analysis exhibits that the pure silver nanoparticles were grown in a single phase (face-centered cubic structure). Particle size was confirmed by the TEM images of the well dispersed sample. This method can also be facilitated for other metals such as gold (Au), copper (Cu), palladium (Pd) and platinum (Pt).
