▎ 摘　　要

NOVELTY - Preparation of tungsten disulfide/carbon nanofiber/graphene composite material comprises mixing polyacrylonitrile powder and N,N-dimethylformamide, electrostatic spinning, oxidizing, soaking in graphene oxide solution, carbonizing under inert gas atmosphere, dissolving ammonium thiotungstate and hydrazine hydrate in organic solvent, adding carbonized graphene composite material, solvothermal reacting, and heat treating under inert gas atmosphere. USE - Method for preparing tungsten disulfide/carbon nanofiber/graphene composite material used for e.g. high-performance electrocatalytic material, lithium ion batteries and solar cell electrode material (all claimed). ADVANTAGE - The material is stable, has improved conductivity, and enhanced mechanical performance.
