| Popis: | In this paper, we report the synthesis of copper sulfide (CuxS) nanoparticles (NPs) with different stoichiometry from different Cu(II) thiosemicarbazone complexes. The complexes were used as single-source precursors (SSPs). Solvothermal decomposition of SSPs at 198 °C temperature in the presence of ethylene glycol (EG) leads to the formation of CuxS NPs. Obtained NPs were characterized by different techniques like UV–visible and photoluminescence spectroscopy, Powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). They are spherical in shape and shows good photoluminescence properties. The XRD patterns indicate that the solvothermal decomposition of different precursors results into the formation of NPs having different phases, viz., Cu2S, CuS, and mixed Cu2S/CuS. It is observed that the mixed-phase NPs show good photocatalytic activity towards degradation of Methylene Blue (MB) dye compared to other NPs. The composite of mixed Cu2S/CuS phase with carbon nanoparticles (CNPs) was prepared. It is further observed that this composite not only shows drastic increase in degradation of MB but also shows its sonocatalytic degradation. |
