Abstract: An exemplary embodiment relates to a nano-color coating layer and a method of forming the same, and more particularly, to a color structure representing a back side-reflection color with metallic luster and high chroma when observed in a substrate incident mode by greatly enhancing light absorbance at a specific wavelength using a resonance structure in which a light absorbing material is inserted between a transparent substrate and an upper mirror layer. In addition, the exemplary embodiment provides a color structure which controls metallic luster and texture of a high-chroma color from gloss-semi-gloss-matte texture in various ways by introducing a haze surface structure in which light scattering occurs on at least one surface of the transparent substrate.

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.
