Abstract:
A rational interfacial structure design strategy enables the construction of a Z-scheme photocatalyst by integrating a Co9S8 interlayer via cation exchange. This transforms a Type-I ZnS-CdS heterojunction into a Z-scheme ZnS-Co9S8-CdS heterojunction, enabling ultrafast charge transfer (0.198 ps). The optimized catalyst exhibits a high HER rate of 13 451 µmol g-1 h-1 and retains 97.1% efficiency after 24 hours.
