Insight into the Effect of Highly Dispersed MoS2 versus Layer-Structured MoS2 on the Photocorrosion and Photoactivity of CdS in Graphene–CdS–MoS2 Composites
Abstract
Designing a semiconductor CdS-based photocatalyst for H 2 evolution from water with high activity and stability is extremely desirable for practical application. We report the important morphological and structural influence of MoS 2 cocatalyst on the photocorrosion and photoactivity of CdS that is carpeted on a graphene (GR) surface. Homogeneous dispersion of MoS 2 nanoparticles by a controlled photodeposition (PD) method produces the GR–CdS–MoS 2 (PD) composite, which does not have the characteristic stacked layer structure of MoS 2 . However, this GR–CdS–MoS 2 (PD) composite exhibits much higher activity and particularly antiphotocorrosion than the hydrothermal synthesized GR–CdS–MoS 2 (HT) counterparts, which feature the characteristic MoS 2 layer structure, toward photocatalytic water splitting under visible light irradiation. The characterization results indicate that homogeneous dispersion of tiny MoS 2 for GR–CdS–MoS 2 (PD) markedly improves the separation and transfer of charge carriers and provides the increased number of catalytic active sites afforded by the absence of the stacked layer structure of the MoS 2 cocatalyst. This work provides direct evidence of the negative effect of the stacked layer structure of MoS 2 on boosting the activity and photostability of CdS on the GR surface, which would guide the more rational use of MoS 2 and GR as cocatalyst toward achieving a highly active and stable semiconductor-based composite photocatalyst for H 2 evolution.

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.
