The synthesis of Ag, Cu and Ag-Cu nanoparticles with divalent disulfur ligand by the Brust method were obtained. The metals were reduced by sodium borohydride and stabilized with 2,2'-dithioethanol (L1), N,N'-dithiophtalimide (L2) and triphenylmethanesulfenamide (L3). The nanoparticles were characterized by TEM, EDX, electron diffraction and FTIR. The stability of the colloids at room temperature was also measured. We can observe a high stability for the colloids dispersion with L3 ligand (>1 week by AgCu-L3, Ag-L3 and Cu-L3). We found TEM studies show a size distribution between 9.7 and 15.8 nm, depending on the ligand. Electron diffraction analysis for the metallic nanoparticles shows the presence of Ag 2 S, Ag, CuO and bimetallic compounds such as CuAgS. The active solids were obtained by solvent evaporation from the nanoparticles dispersed to 50 ºC. The FT-IR exhibit the presence of the ligand incorporated in the solid.
