WS3 is primarily explored in advanced materials research, particularly in the field of nanotechnology and electronics. It exhibits promising semiconducting properties, making it suitable for use in field-effect transistors and photodetectors. Due to its layered structure, WS3 can be exfoliated into ultrathin two-dimensional sheets, which are integrated into flexible electronics and optoelectronic devices. It is also investigated for catalytic applications, especially in hydrogen evolution reactions, where it shows potential as a low-cost alternative to platinum-based catalysts. Additionally, WS3-based composites are studied for energy storage systems, including lithium-ion and sodium-ion batteries, owing to their ability to facilitate ion intercalation.
