A facile, self‐sacrificing template route has been developed to synthesize spinel MIIIn2S4 (MII = Mn, Zn, Cd, Fe, Co, Ni) and MIIn5S8 (MI = Cu, Ag) porous microspheres. The BET surface areas of the products are around 70 m2 g–1. The urchin‐like In2.77S4 microspheres precursor acts as both starting material and template to confine the growth of the final products. The phase structures and morphologies of the products were characterized by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and electron diffraction. Possible formation process and growth mechanism for the porous structure are proposed based on the experimental results. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

“…[74] The largest synthetic MoS 2 tube grown without using a template was 11 lm in diameter and 2 mm in length. [51] Optimization of the growth process or use of nanosized templates enables the production of tubes with nanosize diameter. As an example, the change of stoichiometry from transition metal di-chalcogenide towards tri-chalcogenides considerably reduces the average diameter of MoS 2 and WS 2 NTs.…”

Since the first report on the synthesis of inorganic WS2 nanotubes in 1992, the number of articles on the successful growth of different inorganic nanotubes has increased rapidly, emphasizing the importance of this field for nanotechnology. Although there are some geometrical similarities to carbon nanotubes, inorganic nanotubes are distinguished by important peculiarities, from their growth mechanisms to the physical and chemical properties that are attractive for potential applications. Their structural properties, which are important for such applications, are discussed in this review.

Abstract:The synthesis of inorganic nanotubes (INT) from layered compounds of a small size (<10 nm in diameter) and number of layers (<4) is not a trivial task. Calculations based on density functional tight-binding theory (DFTB) predict that under highly exergonic conditions, the reaction could be driven into a "window" of (meta-) stability, where 1-3-layer nanotubes will be formed. Indeed, in this study, single-to triple-wall WS 2 nanotubes with a diameter of 3-7 nm and a length of 20-100 nm were produced by high-power plasma irradiation of multiwall WS 2 nanotubes. As target materials, plane crystals (2H), quasi spherical nanoparticles (IF) and multiwall, 20-30 layers, WS 2 nanotubes were assessed. Surprisingly, only INT-WS 2 treated by plasma resulted in very small, and of a few layers, "daughter" nanotubules. The daughter nanotubes occur mostly attached to the outer surface of the predecessor, i.e., the multiwall "mother" nanotubes. OPEN ACCESSInorganics 2014, 2 178They appear having either a common growth axis with the multiwall nanotube or tilted by approximately 30° or 60° with respect to its axis. This suggests that the daughter nanotubes are generated by exfoliation along specific crystallographic directions. A growth mechanism for the daughter nanotubes is proposed. High resolution transmission and scanning electron microscopy (HRTEM/HRSEM) analyses revealed the distinctive nanoscale structures and helped elucidating their growth mechanism.
