摘要: This paper reports on the biosynthesis of copper nanoparticles (NPs) using extract Euphorbia esula L leaves as reductant and stabilizer without any surfactant. The catalytic efficiency prepared Cu NPs for reduction 4-nitrophenol ligand-free Ullmann-coupling reaction is discussed. were characterized with UV-vis, XRD TEM methods. method has advantages high yields, simple methodology, elimination ligand easy work up.
