Electrode for Evolution of gaseous products in Electrochemical cells comprising a First catalytic composition which is obtained by thermal descomposicon precursor; Preparation method; and electrolytic cell.

摘要

The invention relates to a method for the reactivation of an exhausted electrode for evolution of gaseous products in electrolysis cells consisting of a metal substrate and an exhausted catalytic coating, comprising the deposition of an outer catalytic composition as a mixture of oxides by reactive sputtering of iridium and ruthenium onto said exhausted catalytic coating.
