A new study published in Frontiers in Energy developed a novel electrode composed of perovskite material La0.6Sr0.4MnO3-δ (LSM) combined with Ce-Mn-W composite oxides, using (Ce0.90Gd0.10)O1.95 (GDC) as a support. Through oxygen species engineering and interfacial synergistic effects, they significantly improved the efficiency and stability of the EOCM process. The composite electrode stabilizes reactive oxygen species (such as O22-) during the oxygen evolution reaction (OER), while enhancing methane adsorption capacity, thereby facilitating C-H bond activation and C-C bond formation. This breakthrough addresses the bottleneck of balancing selectivity and activity in traditional catalysts.Efficient Electrochemical Methane Coupling Enabled by Stabilized Oxygen Species During Oxygen Evolution in a Solid Oxide Electrolyzer Integrated with CO2 Electrolysis
