· Co4 Mo8 S16

Co₄Mo₈S₁₆ is a layered transition metal sulfide compound combining cobalt and molybdenum—a research-stage semiconductor material belonging to the broader family of dichalcogenides and polymetallic sulfides. This material is primarily investigated for electrocatalytic applications, particularly as an earth-abundant alternative to platinum for hydrogen evolution and oxygen reduction reactions in electrochemical devices. Notable for its mixed-metal composition that can enhance catalytic activity compared to single-metal sulfides, Co₄Mo₈S₁₆ remains largely in experimental development, with potential relevance to engineers designing next-generation energy conversion systems where cost and sustainability are critical constraints.

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.
