Journal Article
Pfeifer, V., Jones, T., Velasco Vélez, J., Arrigo, R., Piccinin, S., Hävecker, M., …Schlögl, R. (2017). In situ observation of reactive oxygen species forming on oxygen-evolving iridium surfaces. Chemical Science, 8(3), 2143-2149. https://doi.org/10.1039/c6sc04622c

Water splitting performed in acidic media relies on the exceptional performance of iridium-based materials to catalyze the oxygen evolution reaction (OER). In the present work, we use in situ X-ray photoemission and absorption spectroscopy to resolve...
