We present an overview of the electrochemical reduction of oxygen in water, focusing on carbon-based and modified carbon electrodes. This process is of importance for gas sensing, in fuel cells and in the electrosynthesis of hydrogen peroxide.

Keywords: Electrochemical reduction, Oxygen, Carbon-based modified electrodes
