Figure 2 Comparison with original text after correction: Figure 2a better shows that MoS2 presents a monodisperse structure. Figure 2c better shows the composite morphology of MoS2 and graphene. It more clearly expresses the meaning of this sentence: “The MoS2/Gr sample is shown in Fig. 2c and d. Many MoS2 flower-like nanoparticles assembled along the plane direction and formed a sheet with a thickness of approximately 1.5 μm.” Figure 2e can more clearly show the three-dimensional hierarchical structure of MoS2/GrF composites.
