Solution routes to nanoscaled tungsten chalcogenides are of interest for catalysts, lubricants, solar, and battery applications. Recently we developed a general solution route to metal chalcogenide nanomaterials from metal alkoxides (cadmium & alkaline earths) and have extended it to include the WEx. Tungsten disulfide (WS2) nanomaterials are accessible through a solvothermal reaction between tungsten (V) ethoxide and hexamethyldisilathiane. TEM/PXRD of the as prepared materials revealed monolayered WS2. Thermal treatment, under an inert atmosphere, formed bulk WS2. Full details on the synthesis and characterization will be discussed. This work was supported in part by The University of New Mexico's Nanoscience & Microsystems REU Program and by the Laboratory Directed Research and Development (LDRD) program at Sandia. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.
