Title:
ELECTRODE FOR OZONE GENERATION
Document Type and Number:
WIPO Patent Application WO/2024/004776
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrode for ozone generation, the electrode exhibiting excellent ozone generation efficiency even in a neutral aqueous solution such as city water, while having excellent durability. An electrode for ozone generation according to the present invention is an electrolysis electrode which is composed of: an electrode base material that is formed of titanium or a titanium alloy; and a catalyst layer that is arranged on the electrode base material and contains, in terms of metals, 79.0% by mole to 90.0% by mole of tin oxide, 7.0% by mole to 17.0% by mole of antimony oxide, and 0.1% by mole to 6.0% by mole of nickel oxide.
