· LaAuO2S

LaAuO₂S is a mixed-valence lanthanum gold oxide sulfide ceramic compound that combines rare-earth, noble metal, and chalcogen elements in a layered or complex crystal structure. This is a research-phase material primarily investigated for its potential electrochemical and photocatalytic properties rather than established industrial production. The material family shows promise in energy conversion applications such as fuel cells, electrocatalysis, and photocatalytic water splitting, where the combination of lanthanum's rare-earth chemistry, gold's catalytic activity, and sulfur's redox versatility offers potential advantages over conventional oxide ceramics, though practical applications remain in early development stages.

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.
