abstract = "The evolution of TiO2 nanotubular morphology, synthesized in a
mixture of fluorinated ethylene glycol and glycerol electrolyte,
was studied as a function of the anodization time. The samples
were characterized by FEG-SEM, XRD, XPS, UV-Vis and EIS. The
formation of single-or double-walled TiO2 nanotube structure can
be efficiently controlled by the anodization time. For anodization
times less than 30 minutes, a compact oxide layer is formed,
followed by double-walled nanotube formation up to 120 minutes and
single-walled nanotubes up to 240 minutes. XPS analyses show that
the samples obtained with short anodization time have a high
carbon content and oxygenated surface species compared to the
longer-time anodized sample; however, binding energy peaks for Ti
2p remained invariant. The performances of TiO2 nanotubular
photoelectrodes were evaluated in photoelectrochemical water
splitting where TiO2 nanotubes anodized for 120 minutes presented
the best performance that was related to their optimal morphology
and charge transportation.",
