Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a dimensionally stable titanium-based iridium oxide electrode, its electrochemical preparation method and application. Background technique

[0002] Titanium metal is a commonly used catalyst support because of its good electrical conductivity and corrosion resistance. At present, a large number of studies have shown that titanium-based iridium oxide IrO x / Ti electrodes have shown good application potential in many electrochemical engineering fields, such as electrocatalytic oxidation, biomedical applications, hydrometallurgical metal recovery, and electroosmotic dehydration. Titanium-based iridium oxide IrO x The / Ti electrode has excellent activity and stability in catalyzing the oxygen evolution reaction (Oxygen Revolution, OER) in acidic electrolyzed water. Titanium-based metal oxide coated electrodes are also called Dimensionally Stable Anodes (DSA), and th...
