In situ observation of reactive oxygen species forming on oxygen-evolving iridium surfaces (2016)
Journal Article

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...

Pd supported on carbon nitride boosts the direct hydrogen peroxide synthesis (2016)
Journal Article

Herein, the development of an improved Pd on
carbon nitride catalyst for direct H2O2 synthesis from the
elements is reported. Microcalorimetric CO chemisorption is used to characterize the chemical speciation of the Pd-selective and -unselective si... Read More about Pd supported on carbon nitride boosts the direct hydrogen peroxide synthesis.

Tremendous effort has been devoted towards elucidating the fundamental reasons for the higher activity of
hydrated amorphous IrIII/IV oxyhydroxides (IrOx) in the oxygen evolution reaction (OER) in comparison with
their crystalline counterpart, ruti... Read More about Reactive oxygen species in iridium-based OER catalysts.

Characterization of platinum and iridium oxyhydrate surface layers from platinum and iridium foils (2016)
Journal Article

Platinum and iridium polycrystalline foils were oxidized electrochemically through anodization to create thin platinum and iridium hydrous oxide layers, which were analyzed through laboratory photoelectron spectroscopy during heating and time series...
