Copper hydroxide nanowires were synthesized from copper chloride dihydrate and sodium hydroxide in the presence of Pistachio leaf extract at room temperature. The results of scanning electron microscopy (SEM) exhibited that the copper hydroxide Cu(OH)2 are nanowires in shape and having an average diameter of ca. 10 nm and lengths of up to 500 nm . The Fourier transfor infrared spectroscopy (FT-IR) results examined the bioactive functional groups , which acts as dispersing, binding and capping agent for the copper hydroxide nanowires. X-ray diffraction (XRD) spectra confirmed the copper hydroxide nanoparticles crystalline in nature. The current research introduces a new, simple, and rapid route for the in –laboratory synthesis of copper hydroxide nanowires. This facile and green approach may provide a useful tool to large scale synthesis other copper nanoparticles that have potential biotechnology.

In this paper, a green method is reported for synthesis and characterization of zinc oxide nanosheets using Olea europea leaf extract. ZnO nanosheets were characterized by UV-vis absorption spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The UV-vis absorption spectrum shows an absorption band at 374 nm due to ZnO nanosheets. XRD characterize the final product as highly crystalline ZnO with sizes in the range 18-30 nm. The SEM results reveal a presence of network of randomly oriented ZnO nanosheets or nanoplatelets with an average size of 500 nm and thicknesses of about 20 nm. This facile and green approach may provide a useful tool to large scale synthesis other nanoparticles that have potential biotechnology.
