Abstract

Nanoparticles are generally prepared by a variety of chemical methods which are not environmentally friendly. Silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) were successfully synthesized, respectively from AgNO3 and HAuCl4 through a simple eco-friendly route using the juice of Citrus reticulata fruit as reducing as well as capping agent. AgNPs and AuNPs were carried out at 25, 55, 25 and 50 o C respectively. Nanoparticles were characterized with the help of UV–Vis, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Energy Dispersive X-ray Analysis (EDAX), and Scanning electron microscopy (SEM)..
