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.
Claims13
A method for producing molybdenum disulfide crystalline structures, comprising the steps of:
- providing MoS2 having impurities at a concentration of 1% or less by weight and a mineralizer solution to a first zone of an inert reaction vessel in an autoclave;
- dissolving the MoS2 into the mineralizer solution by heating the first zone to a first temperature at a pressure;
- and
- precipitating MoS2 on a seed crystal in a second zone heated to a second temperature that is less than the first temperature.
