Anodic fast-growth of highly ordered hexagonal arrays of TiO2 nanotubes by a single anodization step
Highly-ordered TiO2 nanotubes (NTs) have gained much importance for application in hydrogen production by water splitting (photoelectrochemical cells) and the dye-sensitized solar cells (DSCs) [1,2]. The TiO2 NTs can be synthesized using a titanium foil in fluoride containing electrolytes via electrochemical anodization method. The NTs geometry depends on different anodizing parameters (electro...
متن کاملGrowth, detachment and transfer of highly-ordered TiO2 nanotube arrays: use in dye-sensitized solar cells.
In the present work, we report a simple method of making glass-based dye-sensitized solar cells (DSSCs) with individual free-standing TiO2 nanotube arrays.
متن کاملIdeally Hexagonally Ordered TiO2 Nanotube Arrays
Ideally hexagonally ordered TiO2 nanotube layers were produced through the optimized anodization of Ti substrates. The Ti substrates were firstly covered with a TiN protecting layer prepared through atomic layer deposition (ALD). Pre-texturing of the TiN-protected Ti substrate on an area of 20×20 μm2 was carried out by focused ion beam (FIB) milling, yielding uniform nanoholes with a hexagonal ...
متن کاملMorphology and Microstructure of As-Synthesized Anodic TiO2 Nanotube Arrays
The as-grown structure of electrochemically synthesized titania nanotube arrays is investigated by scanning electron microscope (SEM) in combination with transmission electron microscope (TEM) as well as X-ray diffraction (XRD). The analysis reveals a preferred growth direction of the nanotubes relative to the substrate surface and the well control on the nanotube arrays morphology. The crystal...
متن کاملEnhanced Biocompatibility in Anodic TaOx Nanotube Arrays
This study first investigates the biocompatibility of self-organized TaO x nanotube arrays with different nanotube diameters fabricated by electrochemical anodization. All as-anodized TaO x nanotubes were identified to be an amorphous phase. The transition in surface wettability with TaO x nanotube diameters can be explained based on Wenzel's model in terms of geometric roughness. In vitro bioc...
