Preparation of black TiO2 by hydrogen plasma assisted chemical vapor deposition and its photocatalytic activity
Abstract
Abstract Black TiO2 attracts enormous attention due to its large solar absorption and excellent photocatalytic activity. An approach assisted by hot filament hydrogen plasma to synthesize the black TiO2 nanostructure is presented in our work. The black TiO2 possesses a larger solar absorption, especially in the visible and near infrared region. The measurement results show that the oxygen vacancy and Ti H are the major impacts to form disorder layer and the coloration of black. High absorption of light and numerous active sites ensure the excellent photocatalytic activity for the black TiO2 in the photo-oxidation of organic molecules in water. Considered that Cr has important effect on the electronic structure of TiO2 reported by some researchers, Cr ions were introduced into the structure of TiO2, but Cr ions play the opposite role for its photocatalytic activity because it plays a role in the recombination of photo-generated carriers.

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.
