  • Sonochemical preparation of copper sulfides with different phases in aqueous solutions
    Kristl, Matjaž ...
    There is a growing interest in the synthesis of nanostructured copper sulfidesdue to their ability to form compounds with various stoichiometries. We report a sonochemical route for the preparation ... of copper sulfides with different compositions in aqueous solutions, using different, general and convenient copper sources such as copper acetate, copper hydroxide or basic copper carbonate and thiourea or thioacetamide as sulfur precursors under ambient air. Phase analysis, purity and morphology of the products were studied by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The results revealed that nanoparticles of covellite, CuS, with crystallite sizes between 7 and 18 nm can be obtained by using different precursors and complexing agents and that chalcocite, Cu2S, can also be prepared sonochemically.
