Electrodo para evolucion de productos gaseosos en celdas electroliticas constituido por un sustrato revestido con una primera y segunda composicion catalitica aplicadas en una pluralidad de capas alternadas; su metodo de produccion; y celda de electrolisis de soluciones de cloruros alcalinos.

摘要

An electrode suitable for chlorine evolution in electrolysis cells consists of a metal substrate coated with two distinct compositions applied in alternate layers, the former comprising oxides of iridium, ruthenium and valve metals, for instance tantalum, and the latter comprising oxides of iridium, ruthenium and tin. The thus-obtained electrode couples excellent characteristics of anodic potential and selectivity towards the chlorine evolution reaction.
