Enhanced photocarrier separation in conjugated polymer engineered CdS for direct Z-scheme photocatalytic hydrogen evolution
Abstract
Abstract High efficiency hydrogen generation from water has been achieved in sulfide-polymer heterojunction. In this work, a novel direct Z-scheme CdS/polyimide heterojunction was fabricated by in situ growth of CdS nanoparticles on polyimide (PI) ultrathin nanosheets through solvothermal method. The highest activity achieved on 15%CdS/PI sample reaches to H2-production rate of 613 μmol h−1 g−1 under visible-light irradiation, which is nearly 5 and 60 times higher than that of neat CdS and 1%Pt/PI. Most importantly, the excellent photostability is also achieved over 15% CdS/PI. The enhanced photocatalytic performance and photostability can be attributed to the direct Z-scheme charge transfer in the intimate interfacial between CdS and PI, which accelerates the charges separation and effective suppress of the photocorrosion in CdS/PI heterojunction. The direct Z-scheme charge transfer mechanism is evidenced by in-situ XPS analysis and time-resolved fluorescence (TRPL) decay. This work highlights the role of polymer in constructing efficient sulfide/polymer heterojunction photocatalyst.

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.
