▎ 摘 要
Single layered two-dimensional (2D) molybdenum sulphide (MoS2) was prepared via hydrothermal synthesis. 2D MoS2 nanosheets were incorporated with 2D nitrogen doped graphene oxide (NGO). NGO/MoS2 composite with 2D-2D electronic transition interactions exhibited the enhanced photocatalytic performance than MoS2. This is due to the formation of heterojunction that heightens the charge separation efficiency and promoted the charge transfer kinetics. XRD shows characteristics peaks of MoS2 and NGO. SEM illustrates the well-defined structure of nano-flower sheets of pure and composite material. HRTEM reveals NGO nanosheets coupled with flower like MoS2 nanosheets facilitating strong interfacial coupling. DRS spectra of composite material show reduction in band gap of MoS2 owing to incorporation of NGO. Formation of strong interfacial coupling and exposure of more active sites in 10.0% NGO/MoS2 composite suppress the charge recombination which is responsible for highest photo activity and photocurrent for strong interfacial charge transfer.
