a X-ray powder diffraction pattern ( A ) The starting material composed of Mo 6 S 4 I 6 nanowires with traces of MoS 2 ( asterisk ) and Mo 6 S 2 I 8 . The two indexed peaks are used for approximation of the unit cell of Mo6S4I6; (B) The final material is composed of pure multiwall MoS2 nanotubes. b Raman spectra: (A) Mo6S2I8 nanowires, (B) Mo6S4I6 nanowires; arrows point traces of MoS2; square dot (see also the inset) shows a position of the characteristic peak at 117 cm-1, (C) MoS2 nanotubes gained by sulfurization of Mo6S4I6 nanowires. c Optical absorption spectra: (A) Mo6S4I6 precursor nanowires; (B) MoS2 nanotubes; (C) MoS2 polycrystalline material (powder). All materials were dispersed in ethanol.
