Na2 Ti4 O8

Na₂Ti₄O₈ is a layered titanate ceramic compound belonging to the family of sodium titanium oxides, which are studied primarily as ion-conducting materials and photocatalysts in research and emerging applications. This material is investigated for energy storage devices (particularly sodium-ion batteries and supercapacitors) where its layered structure facilitates ion transport, and for photocatalytic applications in water treatment and environmental remediation. While not yet widely commercialized in high-volume engineering applications, sodium titanates represent a growing research area as cost-effective alternatives to lithium-based materials and as environmentally benign photocatalysts for sustainable industrial processes.
