“…Similar behavior was observed for composites made with MoS 2 sheets with supported cobalt and nickel NP (98% thiophene conversion at 375°C) [125]. On the other hand, composites derived from INT-WS 2 display much less catalytic activity (about 12% thiophene conversion at 600°C) [126].…”

In the last four to five years, there has been a great resurgence of research on two-dimensional inorganic materials, partly because of the impetus received from graphene research. Unlike graphene, which is a gap-less material, most inorganic layered materials are semiconductors or insulators. Some of them, as exemplified by MoS 2 , exhibit unexpected properties, not unlike graphene, with possible applications. Thus, layered metal chalcogenides are being explored intensely, and MoS 2 is emerging as a wonder material. In this article, we present the synthesis and properties of nanosheets composing single or few layers of these fascinating materials. Besides metal chalcogenides, boron nitride, borocarbonitrides (B x C y N z ), metal oxides, and metal-organic frameworks are also discussed.

“…Attention has also been drawn to other inorganic nanotubes since then owing to their interesting properties. Substantial progress has been made and demonstrated that MoS 2 and WS 2 nanotubes have great potential for applications in scanning probe microscopy [4,5], lubrication [6], catalysis [7,8], field-effect transistors [9], nanocomposites [10], and energy storage [11,12].…”

Single-and double-walled WS 2 nanotubes of small diameter (<10 nm) and few layers (<4) have been synthesized by heating ultrathin W 18 O 49 nanowires and S powders in an H 2 /Ar atmosphere at 840°C. In the process of formation and growth of a WS 2 nanotube, the W 18 O 49 phase transformed first into an amorphous WS 3 structure via the absorption and diffusion of the sulfur atoms to substitute the oxygen atoms, and followed by a phase transition from amorphous WS 3 to 2H-WS 2 by losing sulfur atoms to form the shell of the WS 2 nanotube. IMPACT STATEMENTSynthesis of thin WS 2 nanotubes with single-and doubled-walled structure from ultrathin W 18 O 49 nanowires is developed and their structure and growth are studied using electron diffraction and microscopy.
