Abstract: A method for manufacturing an electrode for hydrogen production using a tungsten carbide nanoflake may include: forming a tungsten carbide nanoflake on a nanocrystalline diamond film by means of a chemical vapor deposition process in which hydrogen plasma is applied; and increasing activity of the tungsten carbide nanoflake to a hydrogen evolution reaction by removing an oxide layer or a graphene layer from a surface of the tungsten carbide nanoflake. Since an oxide layer and/or a graphene layer of a surface of tungsten carbide is removed by means of cyclic cleaning after tungsten carbide is formed, hydrogen evolution reaction (HER) activity of the tungsten carbide may be increased, thereby enhancing utilization as a catalyst electrode.
