Laboratory for Energy Systems Analysis (LEA) LEA is an interdivisional laboratory of the Nuclear Energy and Safety Research Division (NES) and the General Energy Research Division (ENE). It unites specific analytical research concerning diverse energy technologies, that is, nuclear, fossil and (new) renewables, and systems. 29.08.2016 Iridium Oxide for the Oxygen Evolution Reaction: Correlation between Particle Size, Morphology, and the Surface Hydroxo Layer from Operando XAS A simple and scalable method for preparation of well-defined chlorine–free iridium oxide nanoparticles active for oxygen evolution reaction (OER) was developed. Operando X-ray absorption spectroscopy and X-ray photoelectron spectroscopy indicate that OER activity is strongly related to the presence of iridium hydroxo (Ir–OH) species on the surface of iridium oxide nanoparticles. 17.02.2017 IrO2‑TiO2: A High-Surface-Area, Active, and Stable Electrocatalyst for the Oxygen Evolution Reaction We have developed a synthetic approach to highsurface-area chlorine-free iridium oxide nanoparticles dispersed in titania (IrO2-TiO2), which is a highly active and stable OER catalyst in acidic media. Operando X-ray absorption studies demonstrate the evolution of the surface species as a function of the applied potential, suggesting the conversion of the initial hydroxo surface layer to the oxo-terminated surface via anodic oxidation. publist2019_0.pdf publist2019.pdf 23.09.2015 •Energie et climat •7 min Des chemins hydrophiles pour améliorer l’efficacité des piles à combustible Des chercheurs de l’Institut Paul Scherrer (PSI) ont développé un procédé de revêtement qui pourrait améliorer l’efficacité des piles à combustible.
