HIGH-LOAD DURABLE ANODE FOR OXYGEN GENERATION AND MANUFACTURING METHOD FOR THE SAME

摘要

The present invention aims to provide a high-load durable anode for oxygen generation and a manufacturing method for the same used for industrial electrolyses including manufacturing of electrolytic metal foils such as electrolytic copper foil, aluminum liquid contact and continuously electrogalvanized steel plate, and metal extraction, having superior durability under high-load electrolysis conditions. The present invention features an anode for oxygen generation and a manufacturing method for the same comprising a conductive metal substrate and a catalyst layer containing iridium oxide formed on the conductive metal substrate wherein the amount of coating of iridium per time for the catalyst layer is 2g/m2 or more, the coating is baked in a relatively high temperature region of 430 degrees Celsius - 480 degrees Celsius to form the catalyst layer containing amorphous iridium oxide and the catalyst layer containing the amorphous iridium oxide is post-baked in a further high temperature region of 520 degrees Celsius - 600 degrees Celsius to crystallize almost all amount of iridium oxide in the catalyst layer.
