· IrCoO2S

IrCoO2S is an experimental mixed-metal oxide-sulfide ceramic composed of iridium, cobalt, oxygen, and sulfur. This compound belongs to the family of multinary transition metal chalcogenides and is primarily investigated in electrochemistry and catalysis research rather than established engineering applications. The material shows promise in electrocatalytic systems—particularly for oxygen evolution reactions (OER) and hydrogen evolution reactions (HER)—where the combination of precious metal (Ir) and base metal (Co) active sites on a sulfide framework offers potential advantages in activity, durability, and cost-effectiveness compared to pure oxide or pure sulfide catalysts.

Regulatory Screening

Environmental

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.
