LaReO2S

LaReO₂S is a rare-earth oxyulfide ceramic compound containing lanthanum and rhenium, representing an emerging class of mixed-anion ceramics designed to combine the thermal and chemical stability of oxides with the electronic or catalytic properties of sulfides. This material is primarily of research interest for high-temperature applications and advanced catalysis, where the dual anion system offers potential advantages over conventional single-anion ceramics in controlling defect chemistry and functional properties. LaReO₂S belongs to the family of layered oxyulfides being investigated for thermoelectric conversion, photocatalysis, and specialized refractory applications where conventional oxides or sulfides alone fall short.
