Water Splitting into H2 and O2 on New Sr2M2O7 (M = Nb and Ta) Photocatalysts with Layered Perovskite Structures: Factors Affecting the Photocatalytic Activity
Abstract
Sr 2 Ta 2 O 7 and Sr 2 Nb 2 O 7 with similar layered perovskite structure showed activities for water splitting into H 2 and O 2 in pure water without any additives under UV irradiation. The band gaps of Sr 2 Ta 2 O 7 and Sr 2 Nb 2 O 7 were 4.6 and 3.9 eV, respectively. Sr 2 Ta 2 O 7 gave H 2 and O 2 from pure water under UV irradiation even in the absence of a cocatalyst. The activity of Sr 2 Ta 2 O 7 was much increased by loading NiO as a cocatalyst even without pretreatment. The quantum yield of the NiO(0.15 wt %)/Sr 2 Ta 2 O 7 photocatalyst was 12% at 270 nm. On the other hand, native Sr 2 Nb 2 O 7 did not possess the activity. The high activity was obtained for the Sr 2 Nb 2 O 7 photocatalyst when NiO was loaded and pretreated. Factors affecting the photocatalytic activities were discussed by using the Sr 2 Ta 2 O 7 and Sr 2 Nb 2 O 7 powder with similar layered perovskite structure. A predominant factor affecting the photocatalytic behavior of Sr 2 Ta 2 O 7 and Sr 2 Nb 2 O 7 is the conduction band levels formed by Ta 5d and Nb 4d .

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.
