This study aims to explore the potential of transition-metal dichalcogenides (TMDs) as photocatalytic materials in addressing critical global issues of environmental pollution and energy scarcity. TMDs offer a tunable bandgap, high surface area, and excellent physicochemical properties, but their conventional synthesis routes involving toxic solvents present a barrier to widespread application. In this study, a green synthesis approach was adopted using a one-step hydrothermal method to prepare few layer WS2, incorporating a low concentration of carboxymethylated cellulose as a stabilizing agent. The resulting material was characterized using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and UV-Vis-NIR spectrocopy, with a focus on its performance in visible-light-driven photocatalysis dye degradation. Our simple and cost-effective method has the potential to effectively remove impurities from water, contributing to a sustainable and healthier environment.
