SYSTEM OF REMOVING METAL CATALYST ON GRAPHENE

摘要

According to an aspect of the present invention, provided is a device for removing metal catalyst of graphene comprising: a process tank wherein a reaction to accommodate a metal catalyst removing solution and remove a metal catalyst of graphene occurs; a holder (21) which has a bottom vertically arranged to a depth direction of the metal catalyst removing solution in the process tank, and has an aperture and a holder (21) having a side surface portion protruding from the edge of the bottom; and a holder control unit (25) controlling the holder (21) to be moved in one or more than one direction while being completely sunk in the metal catalyst removing solution.
