Abstract
This paper reports the synthesis of TiO2 nanotubes by anodic process. The effects of different electrolyte concentrations on the morphological, structural and vibrational properties of TiO2 nanotubes were studied. Scanning electron microscopy images showed that nanotube inner diameter ranging from 15 to 115 nm could be obtained. At lower concentration, nanotubes were homogenous, and highly ordered. As concentration increased, nanotubes experienced dissolution process, and led to formation of pore-like structure. X-ray diffraction measurements revealed that anatase phase and Ti were present in the samples upon annealing at 500 °C for one hour. The intensity of Raman Eg(1) peak was electrolyte concentration dependent. Full width half maximum value derived from Eg(1) peak was associated with the intensity which was related to the change of TiO2 nanotubes morphological quality. © 2011 Elsevier B.V.
