Abstract
Official abstract text for this publication.
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 10a is composed of a valve metal, and an anode catalyst layer 10b 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 10a.
First claim
Opening claim text (preview).
The invention claimed is: 1. An anode comprising: an anode substrate; and an anode catalyst layer formed on a surface of the anode substrate, wherein the anode substrate comprises at least one valve metal selected from the group consisting of aluminum, chromium, and titanium, and the anode catalyst layer comprises Ir x Ta y Zr z O 2 , where x=7, y=2, z=1, or x=7, y=1, z=2, so that the anode evolves oxygen in a sulfuric acid aqueous solution containing a substance to be hydrogenated dissolved at a concentration higher than 1 mg/L. 2. 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. 3. The anode for oxygen evolution according to claim 1 , wherein the substance to be hydrogenated is toluene and a main product is methylcyclohexane. 4. The anode for oxygen evolution according to claim 1 , wherein the anode substrate comprises titanium.
