▎ 摘　　要

NOVELTY - A multi-edge tungsten sulfide nanosheet/graphene nano composite material comprises one or more layers of multi-edge tungsten sulfide nanosheet and graphene composite structure. The volume ratio of multi-edge tungsten sulfide nanosheet and graphene is 1:1-1:4. USE - Multi-edge tungsten sulfide nanosheet/graphene nano composite material (claimed). ADVANTAGE - The multi-edge tungsten sulfide nanosheet/graphene nano composite material is prepared by easy and simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of multi-edge tungsten sulfide nanosheet/graphene nano composite material, which involves using 1-butyl-3-methylimidazolium tetrafluoroborate, ionic liquid, and L-cysteine and ammonium thiosulfate in ratio of 5:1, and graphene oxide.
