· Na2 Ti2 O5

Sodium titanate (Na₂Ti₂O₅) is an inorganic ceramic semiconductor compound belonging to the titanate family, which combines sodium and titanium oxide phases. This material is primarily investigated in research contexts for photocatalytic applications, ion-exchange processes, and electrochemical energy storage, where its layered crystal structure and semiconducting properties enable functions in environmental remediation and advanced battery technologies. Compared to pure titania, sodium titanate variants offer tunable band gaps and enhanced ion mobility, making them candidates for applications where sodium-ion conductivity or photocatalytic activity under visible light is advantageous.
