Abstract
The <italic>in situ</italic> structural evolution of the catalyst was successfully achieved by <italic>in situ</italic> electrochemical dealloying approach. Direct evidence of O–O bond formation was probed by <italic>operando</italic> ATR FT-IR, suggesting the direct O<sub>2</sub> evolution mechanism.
