Protonic ceramic fuel cells (PCFCs) hold potential for sustainable energy conversion, yet their widespread application is hindered by the sluggish kinetics and inferior stability of cathode materials. Here, a facile and efficient reverse atom capture technique is developed to manipulate the surface chemistry of PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) cathode for PCFCs. This method successfully captures segregated Ba and Sr cations on the PBSCF surface using W species, creating a (Ba/Sr)(Co/Fe/W)O3−δ (BSCFW)@PBSCF heterostructure. Benefiting from enhanced kinetics of proton‐involved oxygen reduction reaction and strengthened chemical stability, the single cell using the optimized 2W‐PBSCF cathode demonstrates an exceptional peak power density of 1.32 W cm−2 at 650 °C and maintains durable performance for 240 h. Theoretical calculations unveil that the BSCFW perovskite delivers lower oxygen vacancy formation energy, hydration energy, and proton transfer energy compared to the PBSCF perovskite. This protocol offers new insights into advanced atom capture techniques for sustainable energy infrastructures.This article is protected by copyright. All rights reserved

The electrochemical CO2 (eCO2)‐to‐multicarbon conversion with higher value is regarded as a potential way to promote the transformation of industrial production and the green balance of carbon cycle. Recently, a series of advances have been achieved in the progress of eCO2‐to‐multicarbon conversion, including the in‐depth exploration of coupling mechanisms, the up‐to‐date development of characterization techniques, and the novel interdisciplinary design strategies of catalysts and electrolytic systems. Therefore, it is essential to systematically overview the eCO2‐to‐multicarbon conversion from fundamentals to industrialization, compensating for the limited and insufficient reviews that have been reported. To fill the aforementioned research gap, this overview is focused on the eCO2‐to‐multicarbon conversion from fundamentals to industrialization. First, the possible catalytic mechanisms for eCO2‐to‐multicarbon conversion are accordingly summarized in the order of eCO2 reduction, small molecule‐coupled eCO2 reduction, and eCO2 tandem conversion. Second, the up‐to‐date in situ characterization technologies assisting the rationalization of coupling mechanisms are presented. Third, the optimizing strategies of catalysts and electrolytic systems are briefly classified for the advance of industrialization process. Finally, challenges and perspectives for the further development of eCO2‐to‐multicarbon conversion are reasonably proposed, aiming to offer insights for the following work in this field.
