· Na2Ti3O7

Sodium titanate (Na2Ti3O7) is a ceramic semiconductor compound composed of sodium and titanium oxide layers, belonging to the family of layered titanate materials with ionic conductivity and photocatalytic properties. This material is primarily investigated in research contexts for energy storage and environmental remediation applications, where its ion-exchange capability and ability to generate reactive oxygen species under light exposure offer advantages over conventional titania-based alternatives. Its layered crystal structure makes it particularly notable for ion intercalation in battery electrodes and as a photocatalyst for water treatment and pollutant degradation.
