“…Among them, the TNT array photoanode presents several advantages for the production of molecular hydrogen. For example, (1) due to light scattering within a porous structure, incident photons are more effectively absorbed than on a flat electrode; (2) the tubular nanoarchitecture results in a large effective surface area in close proximity with the electrolyte, thus enabling diffusive transport of photogenerated holes to oxidizable species in the electrolyte; (3) the relevant structure sizes of the TNT arrays, i.e., half the wall thickness, are about 20 nm, which is less than the retrieval length of crystalline TiO 2 [122], hence bulk recombination is greatly reduced and the quantum yield enhances.…”

Titanium dioxide (TiO 2 ) nanotubes have been reported one decade ago and have proven to be of a great interest in photocatalytic water splitting, as well as gas sensing and antibacterial/cancer treatment. This paper presents an overview on general preparation approaches (chemical treatment, template method and anodic oxidation) of tubular TiO 2 nanoarchitectures and their characterization. Current applications of the nanotubes as photocatalysts are also reviewed.

“…A material can be an efficient photo catalyst if its structure is so organized as to minimize the possibility of recombining the photo generated hole-electron pair. Because the hole recombination length in TiO2 is about 100 nm, the optimal architecture must be a nano-structured material [1]. Consequently, many works have focused on the preparation of TiO 2 nano-rods [2,3], nanowires [4,5] and nanotubes [6].…”

Methyl orange (MO) is an environmental concern because their degradation products are highly toxic to aquatic microorganisms and carcinogenic, also their degradation products are mutagenic to humans. Electrochemical oxidation is one of the promising technologies for the dye wastewater de-pollution, which are obtained extensively attentions because it holds the advantages of total oxidization of dyes to CO2 and H2O. Titanium dioxide has emerged as the leading candidate to provide complete destruction of organic pollutants via heterogeneous photocatalysis that result in total mineralization of many organic pollutants. Though this process offers actual annihilation of the dye moleculesatavery high efficiency, thepost-treatmentrecoveryof TiO2canbecostly. The titanium nanotubes are typically produced by anodic oxidation of the titanium foil in various electrolytes.Degradation of methyl orange (MO) was conducted by electrochemical oxidation method with Ti/TiO2 nanotubes anodes. Were prepared samples of TiO2 nanotubes by anodizing titanium in an electrochemical bath consisting of 1:1 waterglycerol with 0.4% of HF using different conditions: 25V for 8 hours, 30V for 3 hours in the stationary state, 30V 3 hours under ultrasound stirring. The oxidation efficiency was determined by UV-VIS analysis of the electrolyte.

“…The latter trigger reactive radical species with concentration proportional to water-dissolved oxygen [1] giving TiO 2 nanostructures photo-catalytic and ionexchange abilities, [2][3][4] and thus great technological interest for applications such as photo-catalysis, self-cleaning surfaces, and biomaterials [5][6][7]. In order to optimize the narrow UV-absorption gap of TiO 2 to enable excitation under visual part of solar spectrum and thus to improve their photo-catalytic behavior, different modification strategies have been studied over recent years using various electron-donating ligands, mainly organic or rarely inorganic molecules absorbing light within the visible region [8][9][10].…”
