· LiTaO2S

LiTaO₂S is a mixed-anion semiconductor compound containing lithium, tantalum, oxygen, and sulfur, representing an emerging class of materials that combine oxysulfide chemistry with layered or complex crystal structures. This material is primarily of research interest for photocatalytic and optoelectronic applications, where the sulfide component can lower the band gap compared to pure oxides, potentially enabling visible-light absorption and enhanced catalytic activity. The material family is notable for balancing the thermal/chemical stability of oxide frameworks with the extended light absorption and electronic properties typical of sulfide semiconductors, making it a candidate for next-generation energy conversion and environmental remediation technologies.

Export Control

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.
