Green synthesis of copper nanoparticles using Plantago asiatica leaf extract and their application for the cyanation of aldehydes using KFe(CN).

Copper nanoparticles (Cu NPs) were synthesized via a green method by using of Plantago asiatica leaf extract as natural solvent and reaction biomedia under environmentally benign reaction conditions. It was observed that use of Plantago asiatica leaf extract makes a simple, eco-friendly and cost effective method for the preparation of the Cu NPs and can reduce copper ions into Cu(0) within 5min of reaction time without using any stabilizer or surfactant agent. The progress of the reaction was monitored using UV-Visible spectroscopy.

Biosynthesis and application of Ag/bone nanocomposite for the hydration of cyanamides in Myrica gale L. extract as a green solvent.

This study focuses on the green synthesis of the Ag/bone nanocomposite by using Myrica gale L. aqueous extract as a reducing and stabilizing agent and investigation of its catalytic activity in the hydration of cyanamides under environmentally benign reaction conditions in aqueous extract as a green solvent without use of toxic and hazardous chemicals. The green synthesized Ag/bone nanocomposite was characterized by various analytical techniques such as X-ray diffraction analysis (XRD), field emission scanning electron microscope (FESEM), transmission electron microscopy (TEM) images, energy-dispersive X-ray spectroscopy (EDS), elemental mapping, and FT-IR spectroscopy.

Green synthesis of the Cu/ZnO nanoparticles mediated by Euphorbia prolifera leaf extract and investigation of their catalytic activity.

A green synthesis process was developed for the preparation of the Cu/ZnO nanoparticles (NPs) using Euphorbia prolifera leaf extract as a mild, renewable and non-toxic reducing agent and efficient stabilizer without using dangerous, hazardous and toxic materials. The approach of biosynthesis appears to be cost efficient eco-friendly and easy alternative to conventional methods of the Cu/ZnO NPs synthesis. The Cu/ZnO NPs were characterized by FESEM, EDS, elemental mapping, TEM and XRD.
