    • 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/m 2 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.
    • 本发明的目的在于提供一种用于产生氧气的高负荷耐用阳极及其制造方法,其包括电解铜箔,铝液接触和连续电镀锌钢板等电解金属箔的制造以及金属提取 在高负荷电解条件下具有优异的耐久性。 本发明的特征在于用于产生氧气的阳极及其制造方法,其包括导电金属基板和在导电金属基板上形成的含有氧化铱的催化剂层,其中催化剂层每铱涂层的量为2g / m2以上,在430摄氏度〜480摄氏度的相对高的温度区域中进行烘烤,形成含有无定形氧化铱的催化剂层,将含有无定形氧化铱的催化剂层在另外的高温区域进行后烘 在520摄氏度至600摄氏度之间,以使催化剂层中几乎所有量的氧化铱结晶。
