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.
