· Mo3 W1 Se6 S2

Mo3W1Se6S2 is a mixed transition metal chalcogenide semiconductor composed of molybdenum, tungsten, selenium, and sulfur atoms in a layered crystal structure. This material belongs to the family of two-dimensional semiconductors and heterostructures, primarily studied for optoelectronic and catalytic applications rather than established commercial production. The tungsten-molybdenum-chalcogenide family is notable for tunable electronic bandgaps, strong light absorption, and catalytic activity toward hydrogen evolution and CO₂ reduction, making it a candidate material for next-generation photovoltaics, photoelectrochemistry, and heterogeneous catalysis where performance advantages over single-component transition metal dichalcogenides are being explored.

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.
