▎ 摘　　要

NOVELTY - Manufacturing transition metal dichalcogenide-graphene heterojunction electrode comprises transferring graphene onto the electrode, depositing a transition metal layer on the graphene-transferred electrode and injecting a gas containing plasma-treated sulfur (S) onto the electrode on which the transition metal layer is deposited. USE - The method is useful for manufacturing transition metal dichalcogenide-graphene heterojunction electrode. ADVANTAGE - The method significantly reduces electrical performance or catalyst performance; It is possible to provide a transition metal dichalcogenide-graphene heterojunction electrode having a continuous interface because there is no foreign material generated during transfer by directly synthesizing the nide-graphene heterojunction and heterojunction is uniformly at all interfaces; and good reproducibility, process is simple, and economical; has high conductivity of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for catalysts for hydrogen evolution (HER), comprising a graphene heterojunction electrode.
