Fig. 3 (A) Schematic solvothermal synthesis with GO sheets to afford the MoS2/rGO hybrid. (B) SEM and (inset) TEM images of the MoS2/RGO hybrid. (C) Schematic solvothermal synthesis without any GO sheets, resulting in large, free MoS2 particles. (D) SEM and (inset) TEM images of the free particles. (E) TEM image showing folded edges of MoS2 particles on RGO in the hybrid. The inset shows a magnified image of the folded edge of a MoS2 nanoparticle. (F) HRTEM image showing nanosized MoS2 with highly exposed edges stacked on a RGO sheet. Polarization curves (G) and corresponding Tafel plots (H) of different electrocatalysts[26]
