Ag2S quantum dots-sensitized TiO2 nanotube array photoelectrodes
Materials Science and Engineering: B, 2012Abstract Ag2S quantum dots (QDs) were deposited on ordered TiO2 nanotube arrays (TNTAs) using a sequential chemical bath deposition (S-CBD) approach. AgNO3 and thiourea were used as the precursor materials of Ag+ and S2− ions, respectively. The decoration of Ag2S QDs significantly shifted the absorption spectrum of the TNTAs to visible light region ...

Modification of TiO2 nanotube arrays by solution coating
Solid State Ionics, 2009Abstract Packed and sintered titania (TiO 2 ) nanoparticles are conventionally used as a photoanode for dye-sensitized solar cells. As a result, barriers are created for the electron transport and electron-hole recombination due to the large number of interfacial boundaries and voids in such a mesoporous photoanode.

TiO2 Nanotube Arrays: Application to Photoelectrochemical Water Splitting
2009The key to a hydrogen economy is a means to generate hydrogen efficiently and inexpensively on a renewable basis, that is, without the use of fossils fuel. While there are different means to generate hydrogen, photoelectrolysis is often seen as a technique by which we might put the hydrogen in the hydrogen economy.

Photoelectrochemical properties of TiO2/SrTiO3 combined nanotube arrays
Ceramics International, 2013The TiO2/SrTiO3 combined nanotube structure was obtained by the anodization and hydrothermal process. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, UV–vis absorption spectroscopy, etc. The behavior of photoelectrochemical activity in the combined films and pure TiO2 nanotube arrays had been investigated ...

Enhanced field emission from clustered TiO2 nanotube arrays
Applied Physics Letters, 2011Field emission properties of clustered titanium dioxide (TiO2) nanotube arrays have been studied and compared with those of dense, highly aligned TiO2 nanotube arrays. It was found that clustered nanotube arrays showed significant increase of field emission current density (sevenfold) and field enhancement factor (fivefold) compared to regular shape ...

Use of TiO2 Nanotube Arrays for Biological Applications
2009Protein immobilization on solid substrates underlies various experimental approaches in biology and biophysics [1–5]. Immobilized proteins are instrumental in identifying protein–protein, protein–DNA, and protein–molecule interactions for a variety of diagnostic and profiling purposes [5–9].
