· IrKO2S

IrKO2S is an iridium-potassium oxide sulfide ceramic compound that combines transition metal and alkaline elements in a mixed-valence oxide-sulfide structure. This is a research-phase material studied primarily for electrochemical and catalytic applications where iridium's high corrosion resistance and catalytic activity can be leveraged in sulfide-based systems. The material represents an experimental approach to designing bifunctional catalysts that may outperform conventional oxide or sulfide alternatives in oxygen evolution, water splitting, and electrocatalytic processes.

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.
