· Mo3 W1 Se8

Mo₃W₁Se₈ is a mixed transition metal diselenide compound belonging to the family of layered chalcogenides, combining molybdenum, tungsten, and selenium in a stoichiometric ratio. This is primarily a research-stage material studied for its semiconducting properties and potential in optoelectronic and catalytic applications, particularly as a two-dimensional material or nanostructured form. The alloying of molybdenum with tungsten in a selenide matrix is explored to tune bandgap, carrier mobility, and catalytic activity compared to pure MoSe₂ or WSe₂, making it relevant for researchers developing next-generation photovoltaic devices, photodetectors, and electrocatalysts for hydrogen evolution.

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.
