Enhancement of the Photoinduced Hydrophilic Conversion Rate of TiO2 Film Electrode Surfaces by Anodic Polarization
Abstract
Changes in hydrophilicity of TiO 2 film electrode surfaces by UV light irradiation in an aqueous solution were investigated under potential-controlled conditions. Although no change was observed when the electrode potential of TiO 2 was set around its flat-band potential E fb, the photoinduced hydrophilic conversion proceeded at potentials positive of E fb . The hydrophilic conversion rate increased with larger positive potentials, but the addition of hole scavengers decreased the rate, suggesting that the diffusion of photogenerated holes to the surface is the important process for the hydrophilic conversion. Based on these results, we propose a model in which the photoinduced hydrophilicity is initiated by two-hole trapping by a surface lattice oxygen, producing an oxygen defect, followed by the dissociative adsorption of a water molecule at the defect site.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
