Enhanced Interfacial Charge Transfer and Separation Rate based on Sub 10 nm MoS₂ Nanoflakes In Situ Grown on Graphitic-C₃N₄

Herein, sub 10 nm MoS₂ nanoflakes are successfully in situ grown on graphitic-carbon-nitride (MoS₂/g-C₃N₄) through a hydrothermal strategy. The scanning electron microscopy result indicates that the thickness of the MoS₂ nanoflakes is less than 10 nm, which can boost the transport rate of the photoproduced charge during the photodegradation process. Transmission electron microscopy result clearly shows that an excellent interfacial heterojunction is formed between g-C₃N₄ and MoS₂, which will significantly improve the stability of catalysts. Particularly, the optimal 8% MoS₂/g-C₃N₄ product displays significantly enhance catalytic performance and excellent long-term photodurability. These superior photocatalytic properties are attributed to the excellent interfacial heterostructure between MoS₂ and g-C₃N₄, which extends the visible light absorption range, suppresses the recombination, and improves the transfer rate of photoproduced charge.
