Electrocatalysis offers important opportunities for clean fuel production, but uncovering the chemistry at the electrode surface remains a challenge. Here, this work exploits a single-nanosheet device to perform in-situ measurements of water oxidation electrocatalysis and reveal a crucial interaction with oxygen. The obtained in-depth understanding could provide valuable clues for catalysis system design and the in-situ measurement could be also useful to analyze other interfacial reaction processes.
