Graphical abstract: Nanotubes and fullerene-like nanostructures of MoS{sub 2} were synthesized via a microwave-assisted route in solution phase. Highlights: Black-Right-Pointing-Pointer Microwave-assisted route for synthesis of nanotube and fullerene-like nanostructures of MoS{sub 2}. Black-Right-Pointing-Pointer Morphological analysis of the synthesized products. Black-Right-Pointing-Pointer Solvent plays important role in the modification of morphology of MoS{sub 2}. -- Abstract: The paper described the synthesis of nanotubes and fullerene-like nanostructures of MoS{sub 2} through a technically simple, rapid, and energy-efficient microwave-assisted synthesis technique, which involved the use of elemental sulfur dissolved in a mixture of monoethanolamine and hydrazine hydrate as the sulfide source. The microwave induced reaction between the molybdate with sulfide ions, in the presence of hydrazine hydrate in the reaction medium, resulted in the formation of gray colored powders of amorphous MoS{sub 2}. The as-obtained powders were calcined at 600 Degree-Sign C for 2 h and characterized by different techniques. HRTEM analysis of the calcined samples indicated the formation of fullerene-like MoS{sub 2} structures when the starting solution mixture was irradiated with microwave for a period of 200 s, while on 600 s of irradiation of the same revealed the formation of folded sheets like MoS{sub 2} nanotubes. BET surface areas of the calcined samples have been measured and a plausible reaction mechanism for the formation of nanotubes and fullerene-like nanostructures of MoS{sub 2} has been proposed.
