K2TiS3

K2TiS3 is a layered titanium sulfide compound belonging to the family of transition metal chalcogenides, characterized by a structure combining potassium, titanium, and sulfur elements. This material is primarily of research interest for energy storage and catalytic applications, where its layered structure and mixed-valence titanium chemistry offer potential advantages in ion intercalation and surface reactivity compared to conventional oxides. K2TiS3 remains largely experimental, with development focused on electrochemical energy systems and heterogeneous catalysis where sulfide-based materials can provide enhanced electronic conductivity and tunable reactivity.
