Photocatalytic Activity Enhancing for Titanium Dioxide by Co-doping with Bromine and Chlorine
Abstract
Bromine and chlorine co-doped nanocrystalline titanium dioxide are synthesized by a hydrothermal method using titanium chloride in a mixed hydrobromic acid−ethanol system. TiO 2 with anatase, mixed anatase/rutile, rutile, mixed rutile/brookite, mixed anatase/rutile/brookite, and rutile phases are obtained, in that order, by increasing the acidity through addition of HBr. Br - and Cl - co-doping causes the absorption edge of TiO 2 to shift to a lower energy region. The photocatalytic activity of doped TiO 2 with mixed anatase/rutile phases exceeds that of commercial TiO 2 photocatalyst Degussa P-25 for water splitting into H 2 and O 2 under ultraviolet light.

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.
