Hydrothermal Synthesis and Characterization of Flowerlike Molybdenum Disulfide Microspheres
Flowerlike molybdenum disulfide (MoS2) microspheres with diameters around 3–5 μm were successfully synthesized by a traditional hydrothermal solution reaction, using sodium molybdate (Na2MoO4·2H2O), thiourea (CS(NH2)2), oxalic acid (C2H2O4) and bromohexadecyl pyridine (C21H38BrN, CPB) as the precursors. The XRD, SEM, EDS, TEM, HRTEM, SAED and Raman spectra showed that the as-prepared flowerlike MoS2 microspheres are comprised of thin nanosheets, and these nanosheets were connected to each other to epitaxially grow on a basis of the center to form flowerlike microspheres. The effect of the reaction temperature on the formation of MoS2 was investigated in detail. It was found that the addition of bromohexadecyl pyridine played a crucial role in the formation of the flowerlike MoS2 microspheres. Finally, the results of optoelectronic properties indicated that the obtained flowerlike molybdenum disulfide microspheres have potential applications as an effective optoelectronic material.
