dc.description.abstract | With their similar layered structures and complementary physicochemical properties, molybdenum disulfide (MoS2) and graphene nanosheets can be formed into MoS2/graphene heterostructures with improved electrical, optical, catalytic, and electrochemical properties, enabling promising applications. Here, we present a method to prepare MoS2/graphene nanocomposites by liquid-phase exfoliation through the combined processes of high shear mixing and ultrasonication in deionized water without additional additives, under ambient conditions. MoS2/graphene nanocomposites in large quantities can be achieved with a highspeed mixer homogenizer and a tip sonicator by optimizing the processing parameters for shear exfoliation, such as shearing speed, shearing time, ultrasonication time, and the weight ratio of bulk MoS2 to graphite. Optimum conditions are achieved by comparing the graphene concentration produced, I-D/I-G, I-2D/I-G, and E-2g-A(1g) values from the Raman spectra. This is an easily available and facile method, thereby rendering it an efficient route for large-scale industrial production. We also demonstrate the application of the MoS2/graphene nanocomposites to highly sensitive electrochemical sensors. When used to modify an electrode for electrochemical sensing, the MoS2/graphene nanocomposites exhibit excellent electrochemical performances in the detection of morin. | - |
