▎ 摘  要

NOVELTY - Ruthenium-cobalt oxide catalyst comprises at least one metal oxide from ruthenium (Ru) and cobalt (Co) and a carbon-based support supporting the metal oxide. USE - The ruthenium-cobalt oxide catalyst is useful for oxygen evolution reactions (OER) purposes and in electrode for water electrolysis in water electrolysis cell (all claimed). ADVANTAGE - The catalyst improves economic efficiency by reducing the noble metal content, and can shortens bond length between ruthenium and cobalt, and significantly improves catalyst stability in an acidic electrolyte.
