· IrMoO2S

IrMoO2S is a mixed-metal oxide sulfide ceramic compound containing iridium, molybdenum, oxygen, and sulfur. This is a research-phase material under investigation for electrocatalytic and energy conversion applications, particularly as an alternative to precious-metal catalysts in electrochemical systems. The combination of iridium and molybdenum leverages the catalytic strengths of both transition metals while the sulfide component may enhance active site formation and electron transfer, making it a candidate for hydrogen evolution, oxygen reduction, and water-splitting electrodes where cost and performance compete.

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.
