“…During the electrochemical anodization of titanium, several fabrication parameters, including the electrolyte composition, anodization potential, anodization time, temperature, viscosity, water content and pH value of the electrolytes, greatly affect the surface features of the anodic oxide nanostructure. It was reported that in a NH 4 F-based glycerol electrolyte containing a small amount of H 2 O, self-organized TiO 2 nanopore arrays on Ti foil were successfully obtained [13]. The surface morphologies, dimensions and pore density were strongly influenced by the applied potential and anodization temperature.…”

Ti-Ni-Si-O nanostructures were synthesized on Ti10Ni5Si alloy through an electrochemical anodization in electrolyte solutions containing ammonium fluoride (NH4F). The anodic oxide structures were affected by the electrochemical anodization parameters, including the electrolyte viscosity, water content, anodization potential and anodization time. Using an anodization potential of 40 V for 90 min in an ethylene glycol/glycerol electrolyte with 3 vol.% deionized water, highly ordered self-organized nanotube arrays were obtained in the α-Ti phase region of the alloy substrate, with an average inner diameter of 70 nm and a wall thickness of about 12 nm. Self-organized nanopore structures with an average pore diameter of 25 nm grew in the Ti5Si3 phase region. Only etching pits were found in the Ti2Ni phase region. The Ti-Ni-Si-O nanostructures were characterized using scanning electron microscopy and energy dispersive spectroscopy. In addition, a formation mechanism of different nanostructures was presented.

“…Moreover, a bathochromic shift occurs when t a is varied. This shift not only displaces the maximum value of IPCE associated to a wavelength (λ max ), but also to the absorption edge toward longer wavelengths [66]. This effect has also been observed for semiconductors where the crystalline structure has been changed by chemical doping.…”

Titanium oxide nanotubes (TNTs) were anodically grown in ethylene glycol electrolyte. The influence of the anodization time on their physicochemical and photoelectrochemical properties was evaluated. Concomitant with the anodization time, the NT length, fluorine content, and capacitance of the space charge region increased, affecting the opto-electronic properties (bandgap, bathochromic shift, band-edge position) and surface hydrophilicity of TiO2 NTs. These properties are at the origin of the photocatalytic activity (PCA), as proved with the photooxidation of methylene blue.
