| 摘要 |
The invention relates to an electrode for electrolytic processes, in particular to an anode suitable for oxygen evolution comprising a valve metal substrate, a catalytic layer, a protection layer consisting of oxides of valve metals interposed between the substrate and the catalytic layer and an outer coating of oxides of valve metals. The electrode of the invention is particularly suitable for processes of cathodic electrodeposition of chromium from an aqueous solution containing Cr (III). |
