Synthesis of TiO2 nanotube films via pulsed laser deposition followed by a hydrothermal treatment

Abstract

Titanium dioxide nanotube (TNT) films were prepared by pulsed laser deposition (PLD) of P25 and P90 TiO2 nanoparticles onto stainless steel foils followed by a hydrothermal treatment (HT). Heating the PLD films in a TNT precursor solution at 150°C resulted in a well-adhered dense mat of TNTs that were ∼10 nm in diameter with a pore size of ∼4 nm. The TiO2 nanotube films were characterised by SEM, TEM, XRD and Raman spectroscopy. © 2014 Taylor and Francis Group, LLC.
