    • Layered titanate nanotubes thin films were prepared via the hydrothermal reaction of Ti metal flakes with concentrated NaOH solution and controlled post treatment conditions, such as washing with and without hydrochloric acid and calcination. The crystal structures, morphologies, and mechanism of formation of nanostructured titanate film are discussed through TEM, SEM, and XRD studies. Furthermore, potential applications of nanostructured titanates films in photocatalysis and hydrogen storage were investigated.
