Ta2O5 Nanotubes Obtained by Anodization: Effect of Thermal Treatment on the Photocatalytic Activity for Hydrogen Production

Abstract: Freestanding tantalum oxide nanotubes (Ta 2 O 5 NTs) were easily fabricated by controlling only the electrolyte temperature during anodization in a sulfuric acid solution. When the electrolyte temperature decreased, the adherence of NTs to the Ta substrate increased. High electrolyte temperatures facilitated formation of freestanding NTs. Thermal treatment of the freestanding Ta 2 O 5 NTs below 750 °C resulted in an amorphous structure. The orthorhombic crystalline phase appeared only at temperatures higher th… Show more

“…And whereafter, the resulting phosphate-modified BiVO 4 nanoparticle (1 g) was put into a mixed solution consisting of anhydrous ethanol (20 mL), water (5 mL), and HNO 3 (1 mL, 70%) at room temperature under stirring. After that, a certain volume (0.5 mL) of mixed solution of Ti(OBu) 4 and anhydrous ethanol (1:9 by volume) was added dropwise with continuous stirring for 0.5 h. Subsequently, the mixed system was dried at 80°C and then calcined at 450°C in air for 2 h. Thus, phosphate-bridged TiO 2 -BiVO 4 nanocomposite was obtained, denoted as X PB-5T-BV, in which PB indicates phosphate bridge, and 5T means 5 mol ratio percentage of Ti to Bi.…”

“…Photocatalytic water splitting (PC-WS) on semiconductor oxides has become a high-profile research field owing to the high demand for solar energy utilization [1][2][3][4][5][6][7][8]. Among oxide-based photocatalysts reported, BiVO 4 (monoclinic scheelite) is regarded as a promising candidate due to its stability, effective sunlight utilization and high photoactivity for O 2 evolution, and has drawn great attention in recent years [1,[9][10][11][12].…”

“…[20][21][22][23] The sputtering method is quite useful since the size of Pd-NPs can be easily controlled by the current discharge and metal concentration by the time of sputtering. [24][25][26] Moreover, in this method no by-products are generated and only Pd and the support are present in the catalytic material thus allowing a more accurate analysis of the interface Pd-support. Finally, the selective hydrogenation of 1,3-dienes was chosen as a probe to evaluate the properties of the catalysts since this reaction is structure sensitive.…”

“…Gases H 2 , O 2 and CO, CO 2 , CH 4 were analysed simultaneously with a thermal conductivity detector (TCD) and a flame ionisation detector (FID), respectively. 50 Sensitisation of TiO 2 NTs has been done by impregnation method. The NTs were immersed in an RF solution of about 40 ppm and left in contact in dark ambient conditions for 24 h under continuous stirring.…”
