Understanding the dissolution mechanism of oxygen evolution reaction (OER) catalysts is essential for designing efficient and stable electrolyzers. Iridium oxide (IrO 2 ), the most stable single oxide OER catalyst, represents an ideal subject for investigating and decoding the secrets of electrochem...
