Preparation of a visible light-responsive photocatalyst from a complex of Ti4+ with a nitrogen-containing ligand
Abstract
An anatase type of TiO2 photocatalyst containing N atoms was synthesized by a new technique using a complex of Ti4+ with a nitrogen-containing ligand as a precursor. The TiO2-like photocatalyst prepared by calcination of a Ti4+–bipyridine complex exhibited high photocatalytic activity for NOx removal under both ultraviolet and visible-light (λ < 645 nm) illumination. The doping of the N atom into the anatase lattice, which is expected from UV-VIS spectroscopy, XRD, and XPS, is inferred as an important factor for the visible light absorption and NOx removal activity under a wide range of visible light illumination. The bipyridine ligand acted as the source of N and C atoms and additionally inhibited sintering of the photocatalyst during heat treatment.

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.
