In the catalytic reduction atmosphere of H2+CH4+C4H4S, the ball-milled precursor (NH4)2MoS4 is heated to 300C for decomposition. The as-synthesized product is characterized by XRD, SEM, TEM, HRTEM, EDX, and BET. The results show that multi-wall MoS2 nanotubes are obtained. The length of the nanotubes is around 35 mm. The diameters of the nanotubes are homogeneous, with an inner diameter of ~15 nm, an outer diameter of ~30 nm, and an interlayer (002) d-spacing of 0.63 nm. This catalytic thermal reaction occurring at low temperatures is impor-tant for the large-scale preparation of similar transition-metal disulfide nanotubes.
