Preparation and Characterization of CuS Nanoparticles

This study focuses on producing Copper sulphide (CuS) nanoparticles via the sol–gel technique. Characterization methods such as X-ray diffraction (XRD), FTIR, UV spectroscopy, and PL spectroscopy were used to analyze the samples. Various Nanocomposites were created through sol–gel and electro-polishing techniques, yielding core-shell nanostructures via oxidation or sulfidation treatment. These CuS nanocomposites displayed distinct optical absorption peaks reflecting their structural characteristics. Notably, sol–gel methodologies successfully generated copper sulfide (CuS) nanoparticles sized between 30Formula: see textnm and 40Formula: see textnm. This result is verified by XRD data and field emission scanning electron microscope (FESEM) images in this study.
