Green synthesis of copper nanoparticles using aqueous extract of the leaves of Euphorbia esula L and their catalytic activity for ligand-free Ullmann-coupling reaction and reduction of 4-nitrophenol

This paper reports on the biosynthesis of copper nanoparticles (NPs) using extract of the Euphorbia esula L leaves as reductant and stabilizer without any surfactant. The catalytic efficiency of the prepared Cu NPs for the reduction of 4-nitrophenol and ligand-free Ullmann-coupling reaction is discu... View More
