Abstract (en)
Anodes for the generation of electrochemical processes, consisting of a support and an electrocatalytically active top-layer which contains iridium-oxide; a method for producing them and an electrochemical cell in which the anode is applied. The lifetime of such anodes may be prolonged substantially by choosing the oxygen/iridium-ratio between 2.1 and 2.9, the average particle seize of the iridium-oxide being between 3 and 100 nm. The lifetime may be prolonged even further by the presence of an intermediate layer, between support and top-layer, consisting of an oxide of Ta, Nb, Co of Pb or of a mixture thereof, if desired mixed with other metal-oxides. This intermediate layer affixes either directly to the support and the top-layer, or indirectly, via one or more additional intermediate layers.
