Abstract

The invention discloses a ruthenium-palladium-cobalt coating electrode containing a tin-antimony intermediate layer. The surface of the main body of a titanium plate is coated with 3-7 layers of tin-antimony oxide coating as the intermediate layer of the target electrode; the surface of the intermediate layer is coated with There are 15-24 layers of ruthenium palladium cobalt oxide coating as the surface layer of the target electrode. Compared with the traditional ruthenium dioxide coated titanium electrode (RuO2/Ti), the coated titanium electrode of the present invention has higher oxygen evolution potential and lower Excellent chlorine evolution potential and longer service life can effectively improve the current efficiency and electrode service life of the electrocatalytic oxidation reaction system.

Description

technical field [0001] The invention belongs to the electrocatalytic oxidation reaction system anode coating material in the field of electrochemical technology, in particular to a ruthenium palladium cobalt coating titanium electrode containing a tin antimony intermediate layer.
