Abstract
Disclosed is a method for synthesizing single crystalline molybdenum disulfide via a hydrothermal process that minimizes or eliminates carbon byproducts. The method involves providing two components, including a source of molybdenum and a mineralizer solution, to an inert reaction vessel, heating one zone sufficiently to dissolve the source of molybdenum in the mineralizer solution, and heating a second zone to a lower temperature to allow thermal transport to drive the dissolved material to the second zone, and then precipitate MoS2 on a seed crystal.
