· IrIrO2S

IrIrO2S is a mixed-valence iridium oxide sulfide ceramic combining iridium, oxygen, and sulfur phases. This is a research-phase compound studied for electrochemical and catalytic applications, particularly in the oxygen evolution reaction (OER) and water-splitting systems where the dual iridium oxidation states and sulfide incorporation aim to enhance electrocatalytic activity compared to pure iridium oxides or conventional precious-metal 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.
