Copper sulfide (CuS) is a promising material for a variety of applications, including solar cells, lithium-ion batteries, sensors, and catalysts. In this current study, a facile technique for the synthesis of CuS nanocrystallites at modrate temperature 160°) without the use of any template or additives was reported. The reaction was carried out in a pressure reactor for 24 hours. he crystalline nature of the synthesized CuS nanocrystallites was confirmed using powder X-ray diffraction (PXRD), which showed a well-defined hexagonal crystal structure. Fourier transform infrared spectroscopy (FTIR) was used to examine the characteristic molecular vibrations associated with CuS. The surface morphology and structural features of the CuS nanocrystallites were analyzed through scanning electron microscopy (SEM). In addition, the electrochemical behavior of the material was evaluated by cyclic voltammetry, where the recorded voltammograms exhibited reversible redox behavior, indicating good electrochemical activity and highlighting the potential of CuS nanocrystallites for energy-storage applications.
Keywords: Copper sulfide nanomaterials (CuS), cyclic voltammetry (CV), hexagonal plate-like
shape, hydrothermal synthesis.
