Effects of Acceptor Doping to KTaO3 on Photocatalytic Decomposition of Pure H2O
Abstract
It was found for the first time that controlling the charge density in oxide semiconductors with an acceptor was effective for improving the activity to photolysis of H 2 O. Although the photodecomposition activity of NiO supported on nondoped KTaO 3 was negligibly small, doping small amount of acceptors such as tri- or tetravalent cations to KTaO 3 increased the formation rate of H 2 and O 2 . In particular, it was found that NiO supported on KTaO 3 doped with 8 mol % Zr 4+ exhibits higher activity to the photocatalytic decomposition of H 2 O than that of a well-known photocatalyst of Pt/TiO 2 .

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.
