Highly stable dispersions of copper nanoparticles with an average particle size of about 2nm were synthesized via a simple and cost-effective one-pot method with CS2 as a reactant and a solvent as well for synthesizing surface-capping agent and Cu nanoparticles. As-prepared copper nanoparticles were characterized by X-ray powder diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, and Fourier transform infrared ...
