Self-Organized TiO2 Nanotube Layers as Highly Efficient Photocatalysts

Popis výsledku v původním jazyce

In this work we investigate the photocatalytic properties of self-organized TiO2 nanotube layers. The tubes were grown by anodization of titanium in floride containing electrolytes in two different forms as a "short" tubes (length ~500 nm) and as a "long" tubes (length ~2.5 m) with a tube diameter and wall thickness of approx. 100 and 15 nm, respectively. After annealing the tubes to anatase, we used them for the UV light photocatalytic decomposition of Acid Orange 7 and Methylene Blue as a model compounds. For comparison we investigated also compact anodic TiO2 film (thickness ~ 50 nm). The results show that "long" tubes are in photocatalytic decomposition more effective than "short" tubes, which are better than compact anodic TiO2 layer. The decomposition follows pseudo-first order kinetics. We studied also influence of the initial UV light intensity and the starting concentration of Acid Orange 7 for the long tubes. The present result show that self-organized
