摘要

Suitable electrode for oxygen evolution in electrolytic processes, method for fabricating an electrode, and cathodic electrodeposition process of metals from an aqueous solution The invention relates to an electrode for electrolytic processes, in particular a suitable anode for oxygen evolution comprising a valve metal substrate, a catalytic layer, a protective layer consisting of valve metal oxides interposed between the substrate and the catalytic layer and an external coating of valve metal oxides. The electrode of the invention is particularly suitable for chromium cathode electrodeposition processes from an aqueous solution containing cr (iii). 1/1
