Abstract
Official abstract text for this publication.
Metal chalcogenide monolayer nanomaterials can be synthesized from metal alkoxide precursors by solution precipitation or solvothermal processing. The synthesis routes are more scalable, less complex and easier to implement than other synthesis routes.
First claim
Opening claim text (preview).
We claim: 1. A method to synthesize a metal chalcogenide nanomaterial according to the reaction: wherein M is an alkaline earth metal or a transition metal and X is the oxidation state of the metal. 2. The method of claim 1 , wherein the transition metal comprises tungsten or molybdenum. 3. The method of claim 2 , wherein M(OR) x comprises W(OEt) 5 . 4. The method of claim 1 , wherein the alkaline earth metal comprises calcium, strontium, or barium. 5. The method of claim 4 , wherein M(OR) x comprises Ca(OAr) 2 . 6. The method of claim 4 , wherein M(OR) x comprises A E (ONep) 2 and A E comprises strontium or barium and wherein ONep is neopentoxide. 7. A method to synthesize a metal chalcogenide nanomaterial according to the reaction: wherein M is an alkaline earth metal or a transition metal and TOP=E is trioctylphoshine selenide or telluride and X is the oxidation state of the metal. 8. The method of claim 7 , wherein the alkaline earth metal comprises calcium, strontium, or barium. 9. The method of claim 8 , wherein M(OR) x comprises Ca(OAr) 2 . 10. The method of claim 8 , wherein M(OR) x comprises A E (ONep) 2 and A E comprises strontium or barium and wherein ONep is neopentoxide. 11. The method of claim 7 , wherein the transition metal comprises cadmium. 12. The method of claim 11 , wherein M(OR)x comprises Cd(OAr) 2 or Cd(ONep) 2 . 13. The method of claim 7 , wherein the transition metal comprises tungsten or molybdenum. 14. The method of claim 13 , wherein the nanomaterial comprises a layered structure. 15. The method of claim 2 , wherein the nanomaterial comprises a layered structure.
