Abstract
Official abstract text for this publication.
An anode for oxygen evolution that operates at a small overpotential and in a stable manner, and can be used favorably in an organic chemical hydride electrolytic synthesis apparatus. An anode 10 for oxygen evolution that evolves oxygen in a sulfuric acid aqueous solution containing a substance to be hydrogenated dissolved at a concentration higher than 1 mg/L, wherein an anode substrate 10 a is composed of a valve metal, and an anode catalyst layer 10 b containing at least one oxide, nitride or carbide of iridium, and at least one oxide, nitride or carbide of at least one metal selected from the group consisting of elements belonging to groups 4, 5 and 13 of the periodic table is formed on the surface of the anode substrate 10 a.
First claim

1 . An anode for oxygen evolution that evolves oxygen in a sulfuric acid aqueous solution containing a substance to be hydrogenated dissolved at a concentration higher than 1 mg/L, wherein an anode substrate is composed of a valve metal, and an anode catalyst layer comprising at least one oxide, nitride or carbide of iridium, and at least one oxide, nitride or carbide of at least one metal selected from the group consisting of elements belonging to groups 4, 5 and 13 of the periodic table is formed on a surface of the anode substrate. 2 . The anode for oxygen evolution according to claim 1 , wherein the at least one metal selected from the group consisting of elements belonging to groups 4, 5 and 13 of the periodic table is tantalum. 3 . The anode for oxygen evolution according to claim 2 , wherein the at least one metal selected from the group consisting of elements belonging to groups 4, 5 and 13 of the periodic table also contains zirconium. 4 . The anode for oxygen evolution according to claim 1 , wherein an iridium content in the anode catalyst is from 33 to 90% by mass relative to a total mass of all oxides, nitrides and carbides of iridium, and all oxides, nitrides and carbides of the at least one metal selected from the group consisting of elements belonging to groups 4, 5 and 13 of the periodic table. 5 . The anode for oxygen evolution according to claim 1 , wherein an intermediate layer composed of titanium and tantalum is formed between a surface of the anode substrate and the anode catalyst layer. 6 . The anode for oxygen evolution according to claim 1 , wherein the substance to be hydrogenated is toluene and a main product is methylcyclohexane.
