Abstract

In accordance with various embodiments, there are nanostructured materials including WS2 nanostructures and composites of WS2 nanostructures and other materials and methods for synthesizing nanostructured materials. The method can include providing a plurality of precursor materials, wherein each of the plurality of precursor materials can include a tungsten reactant. The method can also include flowing, for a reaction time, a substantially continuous stream of carbon disulfide (CS2) vapor in a carrier gas over the plurality of precursor materials at a temperature in the range of about 700° C. to about 1000 C, wherein the reaction time is sufficient to permit the tungsten reactant to react with carbon disulfide to form a plurality of tungsten disulfide (WS2) nanostructures.
