· JVASP-28466· MoW2Se4S2

MoW₂Se₄S₂ is a mixed transition metal dichalcogenide compound combining molybdenum, tungsten, selenium, and sulfur into a layered crystalline structure. This material belongs to the family of 2D transition metal chalcogenides, which are primarily of research and development interest rather than established industrial production. The compound is investigated for its potential in semiconductor and catalytic applications, particularly for hydrogen evolution reactions, energy storage, and optoelectronic devices where the mixed-metal composition may offer tunable electronic properties compared to single-metal dichalcogenide alternatives.
