Article Synopsis
- CdS quantum dots are promising photocatalysts due to their effective visible light absorption, but their application is limited by photocorrosion issues.
- Researchers developed a composite photocatalyst by integrating CoS nanotubes with CdS QDs, which helps to stabilize the CdS structure and prevent photocorrosion.
- The best-performing composite, with 30% CoS, achieved a hydrogen production rate of 9642.7 μmol·g·h, significantly improving photocatalytic efficiency compared to the original CdS QDs.
The development of an efficient noble-metal-free cocatalyst is the key to photocatalytic hydrogen production technology. In this study, hierarchical Co(OH) nanosheet array-graphene (GR) composite cocatalysts are developed. With Eosin Y (EY) as a photosensitizer, the optimal Co(OH)-10%GR hybrid cocatalyst presents excellent photocatalytic activity with an H production rate of 17 539 μmol g h, and the apparent quantum yield for hydrogen production can reach 12.
