                         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.",
