Adsorbed intermediates in oxygen reduction on platinum nanoparticles observed by in situ IR spectroscopy
- Abstract:
-
The sluggish kinetics of oxygen reduction to water remains a significant limitation in the viability of proton exchange membrane fuel cells, yet details of the four electron oxygen reduction reaction remain elusive. Here we apply in situ infrared spectroscopy to probe surface chemistry of a commercial carbon‐supported Pt nanoparticle catalyst during oxygen reduction. Infrared spectra show potential dependent appearance of adsorbed superoxide and hydroperoxide intermediates on Pt. This strongl...
