▎ 摘　　要

NOVELTY - A multi-functional transition metal-chalcogen compound catalyst electrode (100) comprises a substrate (10) having electrical conductivity, a hydrophilic coating layer (20) formed on the substrate, and a transition metal catalyst (TMC) catalyst layer (30) formed above the coating layer. The substrate is nickel, copper, titanium, tungsten, aluminum, silver, stainless steel, carbon, iron, cobalt, molybdenum and/or graphene. The hydrophilic coating layer is metal nitrate or carbon nitride. The metal nitrate is nickel nitrate. USE - The catalyst electrode is useful in catalyst electrode for water electrolysis. ADVANTAGE - The multi-functional catalyst electrode has excellent electrical conductivity and stability and can be manufactured in a simple and cost-effective manner within a short period of time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing TMCs multifunctional catalytic electrode for water electrolysis. DESCRIPTION OF DRAWING(S) - The drawing shows a view for explaining the structure of a catalyst electrode including a TMCs catalyst layer. 10Substrate 20Hydrophilic coating layer 30TMC catalyst layer 100Catalyst electrode
