Synthesis and Applications of Chalcogenide Nanotubes.

AB - Since the discovery that non-carbon nanotubes can also be synthesized like those of carbon there has been a lot of interest generated in this area, specifically in the case of the transition metal chalcogenide nanotubes. This paper will showcase MoS2 nanotubes, addressing the advances in terms of the synthesis, properties, and applications that have been observed so far. An update on the current status of the field, including the use of aberration-corrected microscopic techniques in understanding the structure and bonding of these nanotubes, which have been proved to be elusive until recently, will be highlighted. Finally, the catalytic properties of these nanotubes will be addressed in the context of the other possible applications as well.
