Effect of length of anodized TiO2 tubes on photoreactivity: Photocurrent, Cr(VI) reduction and H2 evolution

Simultaneously photocatalytic treatment of hexavalent chromium (Cr(VI)) and endocrine disrupting compounds (EDCs) using rotating reactor under solar irradiation

“…In our previous studies, various TiO 2 nanotubes were fabricated on Ti substrates with anodizing method for use as photoeletrode for hydrogen production [28][29][30][31] and photocatalyst for water purification [32,33]. In particular, in a previously performed Cr(VI) reduction with TiO 2 nanotubes [34], we focused on establishing a rotating TiO 2 /Ti reactor to enhance reaction performance and investigated the effects of rotating speed and number of TiO 2 /Ti mesh on the Cr(VI) reduction.…”

Effect of the anodization voltage on the dimensions and photoactivity of titania nanotubes arrays

“… The enhancement was attributed to the high specific surface of the nanotubular structure and to an efficient electron transfer through this highly ordered 1‐D structure. Nanotubes with thickness up to 10 µm were synthesized . Increasing the thickness of the TiO 2 nanotubular films may enhance the absorption of the incident photons, resulting in an increase in photogenerated charge carriers .…”

“…Nanotubes with thickness up to 10 μm were synthesized. [11] Increasing the thickness of the TiO 2 nanotubular films may enhance the absorption of the incident photons, resulting in an increase in photogenerated charge carriers. [12] However, the penetration depth is limited by the absorption coefficient of light into the layer.…”

Preparation of anodized TiO2 photoanode for photoelectrochemical hydrogen production using natural seawater

“…From the SEM images and XRD patterns in Figs. 1 and 2, it can be inferred that the difference of photocurrent from two electrodes is well matched, that is, 'electrode III' with more straight-long tubular structure and higher crystallinity facilitates the transport of electrons activated by the incident UV light to the cathode [34].…”
