Core/Shell Structured La- and Rh-Codoped SrTiO3 as a Hydrogen Evolution Photocatalyst in Z-Scheme Overall Water Splitting under Visible Light Irradiation
Abstract
The effects of preparation methods, calcination times, and La doping concentrations on the crystallinity, visible light absorption, and photocatalytic water splitting performance of Rh- and La-codoped SrTiO 3 (SrTiO 3:La/Rh) were investigated. Applying a two-step solid state reaction in which SrTiO 3 acted as a perovskite-type host produced core/shell structured SrTiO 3:La/Rh, the surface of which was enriched with the dopants. La doping suppressed the formation of oxygen vacancies and inactive Rh 4+ species. Under visible light irradiation (λ > 420 nm), SrTiO 3:La/Rh exhibited 3.5 and 3.8 times higher rates of H 2 evolution in an aqueous methanol solution and during redox-free Z-scheme overall water splitting in combination with Ir/CoO x /Ta 3 N 5, respectively, compared to SrTiO 3:Rh. The solar-to-hydrogen efficiency of the Z-scheme system as measured under illumination with simulated sunlight (AM1.5G) was found to have improved by a factor of 3.

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.
