Abstract
Here, for the first time, we detect reversible structural changes of platinum oxide as an active site in photocatalytic water splitting by operando X-ray absorption fine structure spectroscopy. The platinum-oxygen bond length increases from 2.07 to 2.13 Å and the coordination number reduces from 4.0 to 2.5 between the ex situ and operating photocatalysts.
