Аннотация: Here, we examined the formation of copper nanoparticles in reaction of aqueous solutions of cupric sulfate and sodium dibutyl dithiophosphate, and characterized the products using UV-vis absorption, dynamic light scattering (DLS), zeta potential measurement, TEM and X-ray photoelectron spectroscopy (XPS). Colloidal copper dibutyl dithiophosphate with (C4H9O)(2)PSSCuI composition and the average diameter of 40 nm easily formed and were stable for several days, especially if excessive dibutyl dithiophosphate was used. The size of nanoparticles was smaller at 40 degrees. The UV-vis spectra has absorption maximum at about 420 nm. TEM micrographs and Cu 2p, S 2p O 1s XAS spectra revealed a composition and structure of the particles.
