· JVASP-28550· Mo3Se2S4

Mo₃Se₂S₄ is a mixed chalcogenide compound combining molybdenum with selenium and sulfur, belonging to the family of transition metal chalcogenides. This is primarily a research material under active investigation for semiconductor and photocatalytic applications, rather than an established industrial material. The mixed anionic composition offers tunable electronic properties and enhanced catalytic activity compared to binary molybdenum chalcogenides, making it of particular interest for energy conversion and environmental remediation technologies.
