“…Electrochemical anodizing method is often applied for the synthesis of TiO 2 nanotubes (called also Titania Nanotubes or by their short name TNTs, fig. 5) layers, a type of self organized substrate that became extremely known; much research was dedicated to this subject [57,71,72], due to the multiple and various applications where these nanotubes could be applied. Highly self-organized nanostructures can be also synthesized through electrochemical methods on alumina, gold, zirconium or alloys [73,74].…”

“…Diffusion depends upon differences in concentration between species at the surface of the electrode and in the bulk solution. Finally, convection arises from any mechanical or thermal disturbance in the solution [57]. The repeated experimental procedures and a complete and correct manipulation of the results can lead to electrochemical syntheses of advanced self-organized nanostructures and to the standardization of performing synthesis methods in nanoelectrochemistry.…”

A class of intensively studied materials with application in areas where complex structures with precise geometry are needed (i.e. electronics), are the self-organized nanomaterials. Polymer, metallic and composite self-organized nanomaterials have been in researchers� attention the last decades. They are not only appealing scientifically, by revealing the intrinsic atomic and molecular interactions that might be difficult to detect otherwise but may also hold the key for the development of novel functional structures and devices. The different mechanisms and forces involved in the self-formation of organized nanostructures are discussed in the present manuscript. Further on, key formation fundamentals involved in the fabrication of self-organized nanostructures are described. Between the known manufacturing methods, the electrochemical synthesis is considered extremely simple and cost effective. On the other hand, it involves a wide range of synthesis parameters (e.g. voltage, electrolyte type, temperature, experiment duration, pH etc.) that may lead to the formation of ingenious structures with complex geometries at different length scales. Finally, some representative scientific investigations are mentioned together with applications of self-organized nanomaterials in different engineering and life areas.

“…TNTs have been synthesized by Papanicolaou et al on pure titanium sheets, using the electrochemical anodizing method (Portan, Kroustalli, Deligianni, & Papanicolaou, 2012;Portan, Papaefthymiou, Arvanita, Jiga & Papanicolaou, 2012). The main synthesis methods were presented in Section 27.4.2.3 of this chapter.…”

The electrochemical anodizing method is often applied for the synthesis of TNT layers, a type of self-organized substrate (Portan, Kroustalli, Deligianni, & Papanicolaou, 2012;Portan, Papaefthymiou, Arvanita, Jiga, & Papanicolaou, 2012;Yan-Tao et al, 2003). TNTs are extremely convenient when manufacturing multilayered hybrid nanocomposites because they allow the interaction of two nanostructured substrates, resulting in the creation of an interphase between them; titania hybrid nanocomposites permit the study of nanostructured interphases from a purely scientific viewpoint, and are promising for use in advanced applications.…”

“…It is well established that the titania nanotube growth rate is directly proportional to the duration of anodization [ 3 , 41 , 42 , 43 , 44 , 45 ], the concentration of fluoride ions [ 3 , 4 , 43 , 45 , 46 ], the voltage ( Figure 5 ) [ 3 , 43 , 44 , 45 , 46 , 47 ], and the electrolyte conductivity [ 40 , 46 , 48 ]. Aqueous electrolytes limit the nanotube length to 500 nm for acidic and 2 µm for neutral electrolytes since the rate of Equation (3) is faster in aqueous electrolytes [ 3 ].…”

Anodized TiO2 nanotubes have received much attention for their use in solar energy applications including water oxidation cells and hybrid solar cells [dye-sensitized solar cells (DSSCs) and bulk heterojuntion solar cells (BHJs)]. High surface area allows for increased dye-adsorption and photon absorption. Titania nanotubes grown by anodization of titanium in fluoride-containing electrolytes are aligned perpendicular to the substrate surface, reducing the electron diffusion path to the external circuit in solar cells. The nanotube morphology can be optimized for the various applications by adjusting the anodization parameters but the optimum crystallinity of the nanotube arrays remains to be realized. In addition to morphology and crystallinity, the method of device fabrication significantly affects photon and electron dynamics and its energy conversion efficiency. This paper provides the state-of-the-art knowledge to achieve experimental tailoring of morphological parameters including nanotube diameter, length, wall thickness, array surface smoothness, and annealing of nanotube arrays.
