Ti3+ doped anodic single-wall TiO2 nanotubes as highly efficient photocatalyst

Popis výsledku v původním jazyce

In this work, a two-step treatment of TiO2 nanotube (TNT) layers towards enhanced photocatalytic performance is presented. TNT layers with a thickness of similar to 7 mu m and an average inner diameter of similar to 190 nm were prepared via electrochemical anodization of Ti foil in a fluoride containing ethylene glycolbased electrolyte. To improve the photocatalytic activity of the produced TNT layers a two-step post-treatment was conducted. First, the inner shell of the native double-wall TNT layers was removed via a mild pre-annealing followed by a selective etching treatment of the inner shell in piranha solution yielding single-wall TNT layers. Second, reduction via annealing in H-2/Ar atmosphere was performed. The resulting Ti3+ doped single-wall TNT layers possess 100% enhancement of photocatalytic activity compared to their non-treated counterparts. (C) 2019 Elsevier Ltd. All rights reserved.
