Title:
OXYGEN-GENERATING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2022/018962
Kind Code:
A1
Abstract:
Provided is an oxygen-generating electrode that is equipped with a highly conductive, highly durable catalyst layer capable of long-term electrolysis wherein the catalyst component resists consumption even when electrolysis is performed on an acidic electrolytic solution. An oxygen-generating electrode 10 is provided with a substrate 2 formed of titanium or a titanium alloy, and with a catalyst layer 4 that is disposed on the substrate 2 and is formed of a mixed metal oxide, wherein the catalyst layer 4 satisfies at least one of the following condition (1) and condition (2). Condition (1): contains ruthenium, tin, and an at least trivalent (but excluding tetravalent) polyvalent metal element.
Condition (2): contains ruthenium and tin wherein the ruthenium content is at least 40 mol% with reference to the total content of the ruthenium and tin.
