“…These results point out that despite the fact that a greater proportion of glucose was oxidized, only 28% was, in effect, mineralized to CO 2 and H 2 O. A glucose conversion of 78% in 3 h of reaction is a memorable value, higher than others values obtained for exemple by Zhang and coworkers [28] that obtained 66% of glucose conversion using TiO 2 nanotube photonic crystal after 6 h of photoelectrocatalysis. Probably, in a higher time of reaction, more percentage of glucose could be converted, despite the possibility of mineralization.…”

The present work describes an alternative process for glucose oxidation via photoelectrocatalytic technique using Ti/TiO 2 nanotubes as photoanodes. Under optimum experimental conditions, which entailed 10.0 mM glucose in 0.1 M Na 2 SO 4 , pH 6.60, E app = 1.5 V and UV irradiation we were able to convert 78% of glucose following 180 min of photoelectrocatalysis. Out of that, only 28% was, in effect, converted to CO 2 as detected by total organic carbon removal. During the course of the process, a large part of this glucose was found to be transformed into products among them including Arabinose, Arabinitol, 4ketoglicose, glucohexodialdose, Glucone-d-Lactone, 6-deoxiglucose and Gluconic Acid, where this detection was aided by ion-exchange chromatography with amperometric detection and gas chromatography-mass spectra. The results thus essentially demonstrate that photoelectrocatalys can be considered a suitable alternative in fostering glucose conversion, in aqueous medium, to high added value products using a relatively simple and economic method.

As a promising alternative clean energy to fossil fuels, H2 has been given increasing attention, and efficient H2 production is urgently required. Photocatalytic H2 generation from water splitting (WS) is deemed to be a promising and green route for H2 production. TiO2 has been widely utilized in WS owing to the stability, low cost, corrosion resistance, and environmental safety properities. Nevertheless, two dominant defects (inferior absorption performance in visible light and recombination of photogenerated e−–h+ pairs) still impede the development of TiO2. This review offers a comprehensive overview of the progress of various routes for TiO2 nanostructures (0D–3D) and diversified modifications for enhanced H2 production. Further, the perspectives and opportunities for TiO2 based materials are promoted. Persistent efforts are needed to equip the TiO2 nanomaterials with original advanced commercialization and functionality.

“…Since then, a TiO 2 photocatalyst has attracted much attention and has been widely used in degradation of organic pollutants, CO 2 reduction, and so on [7–12]. As is known to all, TiO 2 can be excited by ultraviolet light, which leads to the low utilization of solar light.…”

“…Besides, its photo-conversion efficiency is very low. To increase the light response region and enhance the efficiency, many approaches have been tried, such as modifying with metal or nonmetal ions [12–16], coupling with other narrow band gap semiconductors [17–19], or sensitizing by various dyes [20–23]. …”

Photocatalytic Oxidation of Propylene on Pd-Loaded Anatase TiO2 Nanotubes Under Visible Light Irradiation

TiO2 nanotubes attract much attention because of their high photoelectron-chemical and photocatalytic efficiency. But their large band gap leads to a low absorption of the solar light and limits the practical application. How to obtain TiO2 nanotubes without any dopant and possessing visible light response is a big challenge nowadays. Orthorhombic titanic acid nanotubes (TAN) are a special precursor of TiO2, which possess large Brunauer-Emmett-Teller (BET) surface areas and strong ion exchange and adsorption capacity. TAN can transform to a novel TiO2 with a large amount of single-electron-trapped oxygen vacancies (SETOV) during calcination, while their nanotubular structure would be destroyed, and a BET surface area would decrease remarkably. And interestingly, SETOV can lead to a visible light response for this kind of TiO2. Herein, glucose was penetrated into TAN by the vacuum inhalation method, and TAN would dehydrate to anatase TiO2, and glucose would undergo thermolysis completely in the calcination process. As a result, the pure TiO2 nanotubes with visible light response and large BET surface areas were obtained. For further improving the photocatalytic activity, Pd nanoparticles were loaded as the foreign electron traps on TiO2 nanotubes and the photocatalytic oxidation efficiency of propylene was as high as 71 % under visible light irradiation, and the photostability of the catalyst kept over 90 % after 4 cyclic tests.
