“…Owing to numerous interstitial oxygen atoms in the salt layer of A (atoms in A-sites)-O(oxygen atoms) rocks, layered R–P oxides (A 2 BO 4 ) are good ion–electron mixed conductor materials and show high electronic conductivities similar to those of chalcocite materials. Zheng et al prepared La 1.5 Sr 0.5 Ni 0.5 Mn 0.5 O 4+δ layered R–P oxides and found that the lowest R p was 0.488 Ω cm 2 at 1073 K. Compared with the pristine La 1.5 Sr 0.5 NiO 4+δ electrode, the La 1.5 Sr 0.5 Ni 0.5 Mn 0.5 O 4+δ electrode had an R p value that was decreased to 81.1%.…”

Highly efficient coelectrolysis of CO 2 /H 2 O into syngas (a mixture of CO/ H 2 ), and subsequent syngas conversion to fuels and value-added chemicals, is one of the most promising alternatives to reach the corner of zero carbon strategy and renewable electricity storage. This research reviews the current state-of-the-art advancements in the coelectrolysis of CO 2 /H 2 O in solid oxide electrolyzer cells (SOECs) to produce the important syngas intermediate. The overviews of the latest research on the operating principles and thermodynamic and kinetic models are included for both oxygen-ion-and proton-conducting SOECs. The advanced materials that have recently been developed for both types of SOECs are summarized. It later elucidates the necessity and possibility of regulating the syngas ratios (H 2 :CO) via changing the operating conditions, including temperature, inlet gas composition, flow rate, applied voltage or current, and pressure. In addition, the sustainability and widespread application of SOEC technology for the conversion of syngas is highlighted. Finally, the challenges and the future research directions in this field are addressed. This review will appeal to scientists working on renewable-energy-conversion technologies, CO 2 utilization, and SOEC applications. The implementation of the technologies introduced in this review offers solutions to climate change and renewable-power-storage problems.

“…In addition, like Co-based perovskite oxides, high Co-containing RP oxides also face the issue of rapid degradation [106]. Some other RP oxides like La 1.5−x Bi x Sr 0.5 Ni 0.5 Mn 0.5 O 4+δ [107], [110], Nd 0.8 Sr 1.2 CoO 4+δ [111], and La 2 NiO 4+δ [112], as shown in Table 1, are also regarded as promising candidates for the air electrodes in SOECs. Further development of the RP air electrodes and basic research into the mechanism of O 2− transportation are required.…”

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.

“…While partially replacing La with Sr failed to yield significant performance improvements, doping Mn at the B site in La 1.5 Sr 0.5 Ni 1− x Mn x O 4+ δ led to increased oxygen vacancy and decreased polarization resistance, according to Zheng et al . 43,44 Other elements like Cu and Bi have also been successfully doped at the B site. 45–47 Pr 2 NiO 4+ δ is another commonly used RP perovskite due to its high anion diffusion and conductivity that rivals La 2 NiO 4+ δ .…”
