Polycrystalline tubulenes and highly disordered sheets of MoS
2 were obtained by precipitating ammonium thiomolybdate solutions [(NH
4)
2MoS
4] with two different tetraalkylammonium surfactants used as templates, hexadecyltrimethylammonium bromide [CH
3(CH
2)
15N(CH
3)
3Br] and tetrabutylammonium hydroxide [(CH
3(CH
2)
3)
4NOH]. Dried and thermally treated samples were characterized by X-ray diffraction, thermal analysis, scanning and transmission electron microscopy. The surfactant-templated hybrid phase (R
4N–MoS
4) showed the (0
0
l) diffraction peak series characteristic of a lamellar mesostructure. The hybrid phase was decomposed at temperatures above 600
°C yielding a MoS
2 phase, which show unusual well-aligned bundles of tubulenes and sponge-like morphology.
