WebAug 4, 2024 · The lattice oxygen evolution reaction (LOER) is commonly viewed as the main reason for the lacking long-term stability of electrode materials in the OER, 9 particularly … Webavailability of the oxygen in the atmosphere and the large thermodynamic driving force of the ORR. There are two possible ways of reductions that can take place. Oxygen can reduce to water by direct 4-electron pathway (Equation 1 and 3) or to peroxide by 2 electron pathway (Equation 2 and 4). The most desirable one is the 4-electron pathway.
