Mechanism of Visible‐Light Photocatalysis in Nitrogen‐Doped TiO2
Abstract
The mechanism behind the visible-light absorption in N-doped titania is resolved through first-principles calculations of the formation energies and excitation energies of the relevant N-related defects in anatase and rutile TiO2. The results indicate that substitutional NO is the source of the visible-light absorption through the photo-excitation of a localized electron from the NO− to the extended conduction-band states.

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.
