  • Porous hollow shell WO/WSnanomaterial and method of preparing same
    Patent number: 10183863
    Abstract: Provided is a method for the preparation of a porous hollow shell WO3/WS2 nanomaterial, comprising: (1) adding a hexavalent tungsten salt to a sol A comprising mesocarbon microbeads, and stirring to obtain a sol B; (2) drying and grinding the sol B, and then heating a resulting powder at 200-500° C. for 0.5-2 hours to obtain a porous hollow shell WO3 nanocrystalline material; (3) placing the porous hollow shell WO3 nanocrystalline material obtained by Step 2 and a sulfur powder separately in a vacuum furnace, controlling such that a degree of vacuum is ?0.01 to ?0.1 MPa and a temperature is 200-500° C., and reacting for 0.5-3 hours to obtain a WO3/WS2 porous hollow shell nanocrystalline material. Also provided is a porous hollow shell WO3/WS2 nanocrystalline material obtained by the method.
