Abstract

This article describes the preparation of copper nanoparticles (Cu-NPs). Natural sources as a green method were used in procedure. Then the properties of the products were compared to each other by XRD spectroscopy. The Copper nanoparticles were prepared using environmentally friendly manner using CuSO4 salt as a source of copper metal with the help two different aqueous extracts of grape and fig leaves as a reducing factor and NaOH solution as a precipitating agent. The copper nanoparticles (Cu-NPs) were obtained by slow addition of plants leaves extracts and sodium hydroxide solution as precipitating agent at room temperature. Copper nanoparticles were characterized by XRD, FE-SEM and TEM techniques. X-ray diffraction (XRD) examination showed that the size of copper nanoparticles was 36.67 and 29.57 nm for grape and fig leaves, respectively. FE-SEM images gave different sizes and shapes of copper nanoparticles at 327.39 and 123.74 nm to sample prepared by grape and fig leaves, respectively. The average size range from approximately 53 to 74 nm for Cu-NPs synthesized using grape leaf extract, and from 33 to 61 for those synthesized using fig leaf extract this confirmed by TEM techniques examination
