· JVASP-109187· FeCoS2

FeCoS2 is an iron-cobalt disulfide compound that belongs to the metal sulfide family, combining ferrous and ferric iron with cobalt in a pyrite-like crystal structure. This material is primarily of research interest for energy storage and catalytic applications, particularly as a precursor or active phase in electrode materials for batteries and electrocatalysts, where the mixed-metal sulfide composition offers enhanced electrochemical activity compared to single-metal alternatives. FeCoS2 is notable in emerging energy technology development rather than established high-volume manufacturing, with potential advantages in cost-effectiveness and performance density relative to precious-metal catalysts.

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.
