· JVASP-18198· TaInS2

TaInS₂ is a ternary ceramic compound combining tantalum, indium, and sulfur, belonging to the family of metal chalcogenides. This material is primarily of research interest for optoelectronic and photocatalytic applications, where its layered crystal structure and semiconducting properties make it a candidate for visible-light-driven catalysis, photodetectors, and energy conversion devices. Engineers consider TaInS₂ over conventional binary sulfides because the three-element composition allows tuning of band gap and crystal properties, though it remains an emerging material with limited industrial-scale production compared to established alternatives.
