摘要：

MoS2 nanostructures including hollow-cage fullerene-like particles, fibrous floccus, and spherical nanovesicles have been successfully synthesized by designed solution chemical reactions of Na2MoO4 and sulfurization reagents such as CS2, Na2S, CH3CSNH2, CSN2H4, and KSCN etc. Possible redox reaction routes have been proposed on the basis of the experimental facts. We have investigated the electrochemical properties of annealed MoS2 samples finding that Mg2+ ions showed better reversibly intercalation/deintercalation cycles in as synthesized MoS2 nanostructures than in bulk MoS2 samples. The solution product of MoS2 and their high-temperature annealing samples were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and resonance Raman spectra.
