Abstract: The invention relates to an electrode for electrolytic processes, particularly to a cathode suitable for hydrogen evolution in an industrial electrolysis process comprising a metal substrate coated with an external catalytic layer containing crystalline ruthenium oxide having a highly ordered rutile-type structure with Ru Ru and Ru O bond length characterised by a Debye-Waller factor lower than a critical value. The catalytic outer layer may contain rare earth oxides, such as praseodymium. The electrode may also comprise an internal catalytic thin layer platinum-based, which gives an enhanced protection against accidental current reversal events.

Abstract: An electrode suitable for use as hydrogen-evolving cathode in electrolytic processes is obtained by thermal decomposition of a precursor consisting of an acetic solution of nitrates of ruthenium and optionally of rare earths. The electrode displays a low cathodic hydrogen evolution overpotential, an improved tolerance to current reversal phenomena and a high duration in industrial operating conditions.

Abstract: The invention relates to an electrode formulation comprising a catalytic layer containing tin, ruthenium, iridium, palladium and niobium oxides applied to a titanium or other valve metal substrate. A protective layer based on titanium oxide modified with oxides of other elements such as tantalum, niobium or bismuth may be interposed between the substrate and the catalytic layer. The thus obtained electrode is suitable for use as anode in electrolysis cells for chlorine production.
