摘要

electrode for the cathodic evolution of hydrogen in electrolytic processes; Method for the production of an electrode The invention relates to an electrode for electrolytic processes, particularly a cathode suitable for hydrogen evolution in an industrial electrolysis process comprising a metal substrate coated with an external catalytic layer containing oxide. Crystalline ruthenium having a highly ordered rutile type structure with ru-ru bond length and ru-o characterized by the fact that it has a lower debye-waller factor than a critical value. The catalytic outer layer may contain rare earth oxides such as praseodymium. The electrode may also comprise a platinum-based internal catalytic thin layer, which provides increased protection against accidental current reversal events.
