Fabrication of multilayered TiO2 nanotube arrays and separable nanotube segments

Journal of Materials Chemistry A, 2014
Layered TiO2 nanotube arrays with new structures were prepared by switching the applied voltage of anodization of Ti. Taking advantage of the solvent effect, in an ethylene glycol electrolyte, arrays with thickness-modulated nanotube walls were prepared; in formamide electrolytes, nanotube arrays on 3-D nanopores, arrays with branched structures and ...

Enhanced photoelectrocatalytic activity in TiO2 nanotube arrays modified with TiO2 nanoparticles

Materials Letters, 2012
Abstract The use of TiO 2 nanotube arrays fabricated by anode oxidation of titanium sheets as a photoelectrocatalyst is limited by low surface activity owing to passive crystallization post-treatment. We report here on a vacuum assisted filling route for modifying TiO 2 nanotube arrays using high-activity anatase TiO 2 nanoparticles as a filling ...

Enhanced photocatalysis on TiO2 nanotube arrays modified with molecularly imprinted TiO2 thin film

Journal of Hazardous Materials, 2010
A molecularly imprinted TiO(2) film was constructed onto the surface of a TiO(2) nanotube (NT) array, getting a novel composite TiO(2) catalyst. Compared with unmodified TiO(2) NT and the non-imprinted film modified TiO(2) NT, the molecularly imprinted film modified TiO(2) NT not only exhibits a much higher adsorption capacity for the target ...

TiO2 nanotube arrays for photovoltaic application

2015
Conversion efficiency of solar cells can be significantly improved by using oriented nanorod- like materials on top of transparent conductive oxide. For this purpose we prepared TiO2 nanotube arrays by anodizing titanium thin film deposited on ZnO covered glass substrate.

Reduced TiO2 nanotube arrays for photoelectrochemical water splitting

Journal of Materials Chemistry A, 2013
We report a facile one-step chemical method to synthesize partially reduced TiO2 nanotube arrays (NTAs). The NaBH4 treatment introduces oxygen vacancies on the surface and interior of TiO2. Oxygen vacancy extends the photocatalytic activity of TiO2 NTAs from the UV to visible light region, and enhances the electrical conductivity as well as charge ...

Stability of TiO2 nanotube arrays in photoelectrochemical studies

International Journal of Hydrogen Energy, 2008
Abstract Photoelectrochemical (PEC) hydrogen generation gives an opportunity to acquire energy by means of clean and renewable resources such as water and solar light. A major problem in the PEC system is the stability of the photoanode material for long-term applications.

TiO2 Nanotube Arrays: Application to Hydrogen Sensing

2009
In this chapter we consider application of TiO2 nanotube arrays to hydrogen gas sensing. Hydrogen, a combustible, widely used industrial gas has great potential for use as a carbon-free chemical fuel. The use of hydrogen, or where hydrogen is an undesired contaminant, requires a monitor suitable for detection of meaningful concentrations.

TiO2 nanotube arrays: hydrothermal fabrication and photocatalytic activities

Journal of Materials Science: Materials in Electronics, 2017
Titanium dioxide nanotube arrays (TiO2 NTAs) with rutile phase have been fabricated successfully via a two-step hydrothermal method. TiO2 nanorod arrays (TiO2 NRAs) are first hydrothermally grown on FTO substrate. Then the TiO2 NTAs can be obtained by controlling the HCl concentration of the hydrothermal etching process.

TiO2 Wedgy Nanotubes Array Flims for Photovoltaic Enhancement

Applied Surface Science, 2011
Abstract In this study, TiO 2 wedgy nanotubes with rectangular cross-sections were fabricated on transparent conductive substrates by using TiO 2 nanorods as the precursor via the anisotropic etching route. TiO2 nanotubes with V-shaped hollow structure and the special crystal plane exposed on the tube wall possess nature of high surface area for ...
