Niobium disulfide (NbS₂) is a layered transition metal dichalcogenide compound belonging to the family of two-dimensional materials. It is primarily investigated in research and advanced materials contexts rather than established industrial production, with potential applications leveraging its layered crystal structure and electronic properties. Engineers consider NbS₂ for emerging technologies in energy storage, catalysis, and nanoelectronics where its low exfoliation energy and tunable electronic behavior offer advantages over conventional materials.
