“…This might be explained by the relatively lower conductivity of the LSGM electrolytes than that of the liquid system, plus the solid electrolyte strongly depends on temperature, and thus they behave like non-liquid electrolytes. 31 In the case of the LSFM-based electrode cells on the LSGM electrolyte, the LSFM, LSFM-Ru, LSFM-Co, LSFM-Fe, and LSFM-Ni had α values of 0.31, 0.31, 0.32, 0.34, and 0.30, respectively. However, these results do not present a major problem because the introduction of a catalyst enhances the electrochemical reaction.…”

“…In addition, La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3−δ (LSCM) is a widely used backbone for infiltration that attracts great interest for SOEC unitization. The infiltration of active materials such as Cu nanoparticles, 44 GDC nanoparticles, 45 and Pd mixed with GDC 46 to LSCM demonstrates the enhanced electrocatalytic performance for CO 2 to CO conversion. Overall, the infiltration of active nanoparticles is not only responsible for improving the electrocatalytic activity but also decreases the ohmic resistance during operation.…”

Conspectus Rapid economic growth and societal development have led to an ever-increasing demand for energy; the excessive exploration and use of fossil fuels have caused an alarming level of carbon dioxide (CO2) emission into the atmosphere, adversely impacting the environment and quality of life in human society. CO2 electrolysis (CO2RR) offers the opportunity to store renewable energy (such as wind, solar, or tidal energy) in the form of chemicals and fuels while reducing CO2 emissions. Through the CO2RR process, a variety of chemicals and fuels can be obtained using different electrocatalysts. Based on the different operating temperature and reaction conditions, CO2 electrolysis can be categorized into low-temperature and high-temperature CO2RR. To date, great effort has been devoted to designing the electrocatalysts that can improve the electrocatalytic performance for CO2RR, including catalytic activity, selectivity, and stability. For low-temperature CO2RR, different approaches have been utilized to optimize the catalyst structure and properties, thereby enhancing the electrocatalytic performance. Given the different working mechanism of high-temperature CO2RR operating in the solid oxide electrolysis cells (SOECs), the cathode materials not only need to meet the requirements of the low temperature but also need to possess high ionic and electronic conductivity, robust coking resistance, and superior compatibility with the electrolytes. In pursuit of this objective, considerable effort is directed toward designing more efficient and effective cathode electrodes for high-temperature CO2RR. Beyond traditional metal and metal oxide materials, perovskite-based materials are emerging as promising candidates due to their unique structure and favorable performance in CO2RR at elevated temperatures. In this Account, we present recent research progress on the design of cathode materials in CO2 electrolysis. We first discuss low-temperature CO2RR electrocatalyst design using different engineering strategies, including structural engineering, defect engineering, phase engineering, doping engineering, interface engineering, and microenvironment engineering. Combined with some representative work from our group and other researchers, the advantages of these diverse strategies are further elucidated, providing a more in-depth understanding of electrocatalyst design. Then, we summarize the cathode materials for high-temperature CO2RR utilization based on the material types such as metal/metal oxides and perovskite-based materials. Further discussion of different approaches, such as infiltration, doping, and in situ exsolution is summarized, aims to improving the electrocatalytic performance of perovskite-based materials for high-temperature CO2RR. Finally, we present current challenges and future prospects of CO2 electrolysis in both the design of cathode materials and the reaction system, with the goal of achieving more profitable applications.

“…This is credited to the presence of the Ni-Cu nanoparticles creating the active electrochemical interface for CO 2 decomposition and enabling high-temperature CO 2 chemisorption/activation. Other secondary phases, such as Ce 0.9 M 0.1 O 2−δ (M = Fe, Co, Ni) [199], Pd-GDC [200], and Cu [201], were also introduced into La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3−δ fuel electrode CO 2 electrolysis performance improvement. GDC nanoparticles (12.8 wt%) were introduced into the SFM fuel electrode by impregnation for CO 2 electrolysis, as shown in Fig.…”

Reliable and economical energy storage technologies are urgently required to ensure sustainable energy supply. Hydrogen (H 2 ) is an energy carrier that can be produced environmentfriendly by renewable power to split water (H 2 O) via electrochemical cells. By this way, electric energy is stored as chemical energy of H 2 , and the storage can be large-scale and economical. Among the electrochemical technologies for H 2 O electrolysis, solid oxide electrolysis cells (SOECs) operated at temperatures above 500 ℃ have the benefits of high energy conversion efficiency and economic feasibility. In addition to the H 2 O electrolysis, SOECs can also be employed for CO 2 electrolysis and H 2 O-CO 2 co-electrolysis to produce value-added chemicals of great economic and environmental significance. However, the SOEC technology is not yet fully ready for commercial deployment because of material limitations of the key components, such as electrolytes, air electrodes, and fuel electrodes. As is well known, the reactions in SOEC are, in principle, inverse to the reactions in solid oxide fuel cells (SOFCs). Component materials of SOECs are currently adopted from SOFC materials. However, their performance stability issues are evident, and need to be overcome by materials development in line with the unique requirements of the SOEC materials. Key topics discussed in this review include SOEC critical materials and their optimization, material degradation and its safeguards, future research directions, and commercialization challenges, from both traditional oxygen ion (O 2− )-conducting SOEC (O-SOEC) and proton (H + )-conducting SOEC (H-SOEC) perspectives. It is worth to believe that H 2 O or/and CO 2 electrolysis by SOECs provides a viable solution for future energy storage and conversion.
