Electroreduction of oxygen
TL;DR: In this article, a diagnostic criterion was developed which allowed a distinction to be made between the two main possible reaction paths in electroreduction of oxygen, and applied to the results obtained in the rotating ring-disc electrode system on gold in alkaline solutions, indicating the absence of the direct four-electron reduction.
