Role of Sn2+ in the Band Structure of SnM2O6 and Sn2M2O7(M = Nb and Ta) and Their Photocatalytic Properties

Abstract

The photocatalytic properties of metal oxides consisting of Sn 2+ with a 5s 2 configuration were studied to find new visible light responsive photocatalysts. The band gaps of Ca 2 Ta 2 O 7, Sn 2 Ta 2 O 7, and Sn 2 Nb 2 O 7 were found to be 4.8, 3.0, and 2.3 eV, respectively. Density functional calculations revealed that the valence band levels formed with Sn 5s orbitals were more negative than those with O 2p orbitals. The result is that niobates and tantalates containing Sn 2+ have narrow band gaps compared with typical niobates and tantalates. SnNb 2 O 6 showed photocatalytic activity for H 2 and O 2 evolution from aqueous solutions containing sacrificial reagents (methanol and Ag + ) under visible light irradiation (λ > 420 nm). Moreover, the photocatalytic activity of SnNb 2 O 6 depended on the material used as the Sn source. SnNb 2 O 6 synthesized from Sn 3 O 2 (OH) 2 showed higher activity for H 2 and O 2 evolution than that synthesized from commercial SnO, which included a small amount of SnO 2 . SnNb 2 O 6 synthesized from Sn 3 O 2 (OH) 2 showed activity for O 2 evolution under visible light, even without IrO 2 as a cocatalyst, whereas that synthesized from commercial SnO showed activity under irradiation only when an IrO 2 cocatalyst was loaded. The activity of SnNb 2 O 6 synthesized from SnO was improved by IrO 2 cocatalyst loading.

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.
