· JVASP-28966· MoW3Se6S2

MoW₃Se₆S₂ is a mixed-metal chalcogenide compound containing molybdenum, tungsten, selenium, and sulfur, belonging to the family of transition metal dichalcogenides and polychalcogenides. This is a research-phase material primarily investigated for its layered crystal structure and electronic properties, with potential applications in catalysis, energy storage, and two-dimensional materials research. The material's multi-element composition enables tuning of band gaps and active sites compared to single-element dichalcogenides, making it a candidate for electrochemical applications where interface chemistry is critical.
