Summary
Molybdenum diselenide (MoSe2) and tungsten diselenide (WSe2) nanotubes were synthesized. These novel nanotubes were produced through chemical reduction or decomposition methods in a hydrogen environment.
Area of Science:
- Materials Science
- Nanotechnology
- Inorganic Chemistry
Background:
- Transition metal dichalcogenides (TMDs) like MoSe2 and WSe2 exhibit unique electronic and optical properties.
- Nanostructured forms of TMDs are of great interest for advanced applications.
- Controlled synthesis of high-quality TMD nanotubes remains a challenge.
Purpose of the Study:
- To develop efficient synthetic routes for molybdenum diselenide (MoSe2) and tungsten diselenide (WSe2) nanotubes.
