Abstract
Provided are novel transition metal dichalcogenides having a platelet structure and comprising a 2H phase region and/or a 3R phase region. The platelets exhibit a narrow size distribution and comparatively high surface area and edge area, which characteristics render the platelets especially suitable for catalysis applications, as well as use in electronic devices. Also provided are methods of synthesizing the disclosed transition metal dichalcogenide platelets.
Claims11
A composition, comprising:
- a population of crystalline transition metal dichalcogenide platelets having the empirical formula MC2, wherein M is a transition metal and C is a chalcogenide,
- each of the platelets comprising a region of 3R phase and a region of 2H phase,
- each of the platelets being characterized as comprising a single atomic layer to a few atomic layers, and
- wherein a majority of the platelets in the population have shapes that are circular, ovoid, American football-shaped, triangular, a 4-sided polygon, a 5-sided polygon, or a 6-sided polygon.
