Voltage- and time-dependent valence state transition in cobalt oxide catalysts during the oxygen evolution reaction

Determining catalyst electronic structures during electrochemical reactions is crucial to understand mechanisms. Here authors perform in operando soft X-ray spectroscopy on a cobalt oxide catalyst during O2 evolution and observe voltage and time-dependent valence state transitions.
