dc.description.abstract | Single-, double-, and triple-layered TiO 2 nanotubes (NTs) array were synthesized by using a voltage pulse-assisted anodic oxidation technique. Morphological and structural evolution of different NTs have been studied by field-emission scanning electron microscopy and X-ray diffraction spectroscopy. “Au/TiO 2 NT layer(s)/Ti” types vertical structured sensors were fabricated and characterized at room temperature (300 K) toward multiple volatile organic compounds (VOCs) and high sensitivity was observed at low concentration (40-160 ppm) of VOCs. Response magnitude was increased with increase of number of layer(s) and found maximum of ~96% at 160 ppm of ethanol for triple-layered NTs. Efficient sensing was achieved for multi-layered TiO 2 NTs due to the benefits of 1) incremental effective surface area and 2) Schottky barrier effect at interlayer junctions. | en_US |
