“…Carbon nanotubes (CNT) with high orientation and low graphitization were formed in TiO 2 nanotube arrays by annealing the latter in carbon atmosphere, constructing a novel functional material with tube-in-tube nanostructure [27]. The formed carbon nanotubes greatly improved the conductivity of the TiO 2 nanotube arrays.…”

Fabrication, properties, and sensing applications of TiO 2 nanotubes have been reviewed, and the highly ordered TiO 2 nanotube arrays made by anodic oxidation in fluoride-contained electrolytes highlighted. The effect of anodization parameters (electrolyte, pH, and voltage) on the titania nanotube size and shape were discussed. The excellent biocompatibility of TiO 2 , the high orientation, the large surface area with tunable pore sizes, as well as the high electron transfer rate along with the nanotubes make TiO 2 nanotube array an ideal substrate for the sensor's fabrication and application. The sensors based on the TiO 2 nanotube arrays for sensing hydrogen, oxygen, humidity, glucose and hydrogen peroxide all exhibited low detection limit, high stability, very good reproducibility and high sensitivity. anodization, TiO 2 nanotube arrays, sensor Citation:Yang L X, Luo S L, Cai Q Y, et al. A review on TiO 2 nanotube arrays: Fabrication, properties, and sensing applications.Nanostructural titania is one of the most widely studied materials due to its unique and excellent properties in optics, electronics, photochemistry and biology, as well as its applications in photovoltaic cells, photocatalysis, and sensors [1-3]. Among the various forms of nanostructural titania, nanotubular titania has attracted increasing interest due to its highly ordered structure and the convenient controlling of the size. Reviews have been given on the fabrication, properties, and applications of titania nanotubes in solar cells [4−6]. It is known that the sensors are increasingly demanded in medicinal, industrial, environmental applications. Sufficient sensitivity, high stability, short response time and long length of life are all key factors for a sensor's application in practice. Generally, the performance of the chemical sensors is optimized by improving the electric properties of the sensor through modifying or selecting more ideal substrates with excellent morphology. With the advent of nanotechnology, it has become evident that nanoscale architectural features of the functional materials applied in sensing can yield superior and unexpected electric behaviors. Recently, TiO 2 nanotube arrays fabricated by anodization were applied in the fabrication of gas sensors and biosensors [3]. The highly uniform morphology, unique orientated growing property, and large surface area with controllable pore sizes as well as the facile fabrication make the titania nanotube array a promising functional material for application in sensors. Furthermore, the photovoltaic property of TiO 2 under UV illumination makes the sensors self-clean the contamination, resulting in a long length of life. Consequently, in this review we focus on the recent developments in the fabrication, modification, and sensing application of the anodized titania nanotubes, which would open up new avenues for the development of sensors.

“…The precisely controllable dimensional features of the nanotube arrays facilitate their application in various fields, including dye-sensitized solar cells [10] , biosensors for measuring H 2 O 2 [11] and glucose [12] using a TiO 2 nanotube array adsorbed with horseradish peroxidase. Efforts have been devoted to doping the TiO 2 nanotubes with nitrogen [13] and carbon [14,15] to enhance the photocurrent response in both the UV and the visible range for applications to water photoelectrolysis, photodecomposing organic pollutants, or fuel cells. Efforts have also been devoted to decorating the nanotubes with noble metals such as Ag, Au, Pt, and Co [16][17][18] to enhance the photoelectric catalytic properties.…”

TiO 2 nanotube (NT) arrays have been prepared by anodic oxidation of a Ti sheet, and carbon-deposited TiO 2 NT arrays have been prepared by annealing TiO 2 NT arrays in carbon atmosphere. The biocompatibility of the as-prepared NT arrays was investigated by observing the growth of osteosarcoma (MG-63) cells on the NT arrays. The application of the TiO 2 NT arrays as a drug delivery vehicle was investigated.Both the TiO 2 NTs and the carbon-modified TiO 2 NTs have good biocompatibility supporting the normal growth and adhesion of MG-63 cells with no need of extracellular matrix protein coating. The one end-opened TiO 2 NTs can be easily filled with drugs, working as an efficient drug delivery vehicle.

Nanotubes constitute an exciting class of one‐dimensional nanomaterials of which carbon nanotubes are recognized widely as materials of importance. The possibility of having inorganic nanotubes was recognized early in the 1990s, accompanied by the report of nanotubes of MoS2 and WS2. Since then, nanotubes of several inorganic materials have been prepared and characterized. While nanotubes of metal chalcogenides and oxides form a high proportion of the inorganic nanotubes investigated hither to, nanotubes of many other materials have also been prepared and characterized. Several synthetic strategies including both physical and chemical methods have been employed, of which the use of templates, precursors, and hydro‐ or solvothermal methods are prominent. In this article, we shall present a brief account of the present status of the synthesis of nanotubes of elemental materials as well as binary and complex metal oxides, chalcogenides, pnictides and carbides.
