Synthesis of Chalcogenide Material (CMnTS) By Hydrothermal Method, Characterization and Its Application

Abstract The present research paper concentrate on the synthesis, characterization and applications of the quaternary chalcogenide material Cu2MnSnS4 (CMnTS) using the hydrothermal method. CMnTS has attracted considerable attention in recent years because of its suitable band gap, excellent optical absorption properties, earth-abundant constituent elements, low cost, and non-toxic nature. These characteristics make it an environmentally friendly and sustainable semiconductor material for renewable energy and electrochemical applications. In this study, CMnTS was successfully synthesized using metal chloride precursors and thiourea as the sulfur source in a Teflon-lined stainless-steel autoclave under controlled temperature and pressure conditions. The hydrothermal technique was chosen due to its simplicity, cost-effectiveness, and ability to produce highly crystalline materials with controlled morphology. The structural properties of the synthesized material were examined using X-ray diffraction (XRD), confirming the formation of the desired crystalline phase. The optical properties were investigated using UV–Visible spectroscopy, which revealed a suitable band gap for solar energy harvesting applications. Furthermore, cyclic voltammetry analysis was carried out to evaluate the electrochemical behavior and charge storage capability of CMnTS. The results indicate that CMnTS exhibits strong potential for application in solar cells, photocatalytic removal of heavy metals from wastewater, and as an anode material in high-energy-density batteries. Overall, this study demonstrates that the hydrothermal method is an efficient and reliable approach for synthesizing high-quality CMnTS suitable for advanced energy-related applications.
