· JVASP-28520· MoW2Se2S4

MoW₂Se₂S₄ is a mixed-metal dichalcogenide compound combining molybdenum, tungsten, selenium, and sulfur in a layered crystal structure. This material belongs to the family of transition metal dichalcogenides (TMDs), which are primarily investigated in research contexts for their unique electronic and catalytic properties rather than established commercial production. The compound is of interest for catalytic applications—particularly hydrogen evolution and electrocatalysis—where the combination of multiple transition metals and chalcogen atoms can create active sites with tunable electronic properties, offering potential advantages over single-metal dichalcogenide alternatives in electrochemical energy conversion systems.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
