Role of electrolyte pH on water oxidation for iridium oxides

Journal of the American Chemical Society, 2023
Understanding the effect of non-covalent interactions of intermediates at the polarized catalyst-electrolyte interface on water oxidation kinetics is key for designing more active and stable electrocatalysts. Here, we combine operando optical spectroscopy, X-ray absorption spectroscopy and surface-enhanced infrared absorption spectroscopy to probe the ...
