Ultrafine sodium titanate nanowires are produced from TiAl alloy precursors via a nonthermal process where Al leaching and Ti oxidation occur simultaneously in an alkaline medium. The obtained nanowires demonstrate a layered crystal structure with a diameter of a few nanometers and exhibit remarkable Sr ion-exchange properties.
