▎ 摘　　要

NOVELTY - The method involves transferring a graphene onto a flexible substrate. A transition metal layer is deposited on the flexible substrate onto which the graphene is transferred. A gas containing plasma-treated sulfur, is injected onto the flexible substrate on which the transition metal layer is deposited. USE - Method for producing transition metal dichalcogenide-graphene heterojunction composite of flexible element (all claimed). ADVANTAGE - The method enables to produce transition metal dichalcogenide-graphene heterojunction composite that has excellent electrical performance and catalytic performance.
