“…The challenges associated with materials are more fundamental in nature, and the degradation mechanism in SOECs is not yet well understood. It is generally agreed that more R&D is warranted toward designing new electrode materials like double perovskites (Shin et al, 2015;Afroze et al, 2019;Tian et al, 2020) or modification of existing electrodes. When CO 2 is added to steam for generation of syngas (mode 2), the issues related to the stability of the electrode become even more challenging.…”

Environmental issues related to global warming are constantly pushing the fossil fuelbased energy sector toward an efficient and economically viable utilization of renewable energy. However, challenges related to renewable energy call for alternative routes of its conversion to fuels and chemicals by an emerging Power-to-X approach. Methane is one such high-valued fuel that can be produced through renewables-powered electrolytic routes. Such routes employ alkaline electrolyzers, proton exchange membrane electrolyzers, and solid oxide electrolyzers, commonly known as solid oxide electrolysis cells (SOECs). SOECs have the potential to utilize the waste heat generated from exothermic methanation reactions to reduce the expensive electrical energy input required for electrolysis. A further advantage of an SOEC lies in its capacity to coelectrolyze both steam and carbon dioxide as opposed to only water, and this inherent capability of an SOEC can be harnessed for in situ synthesis of methane within a single reactor. However, the concept of in situ methanation in SOECs is still at a nascent stage and requires significant advancements in SOEC materials, particularly in developing a cathode electrocatalyst that demonstrates activity toward both steam electrolysis and methanation reactions. Equally important is the appropriate reactor design along with optimization of cell operating conditions (temperature, pressure, and applied potential). This review elucidates those developments along with research and

“…To meet the highly urgent demand for utilizing renewable energy sources, designing efficient and cost-effective catalysts for electrochemical energy conversion has gained attention from academia and industry [1][2][3]. Oxygen reduction and evolution reactions (ORR and OER) are cornerstone reactions for electrochemical conversions between chemical and electronic energy [4][5][6]. For example, ORR wieldy exists in fuel cells and the discharge process of metal-air batteries [7,8], while OER is involved in electrolytic water splitting and metal-air batteries during the charge process [9,10].…”

“…With the rapidly growing concern about the world energy crisis and environmental pollution arising from fossil fuel consumption, electrochemical energy conversion and storage devices (e.g., fuel cells, water electrolysis, metal–air batteries) provide solutions for sustainable energy development in the global era. Since the oxygen evolution reaction (OER) requires proton-coupled and four-electron transfer (4OH – = O 2 + 2H 2 O + 4e – ) in the above-mentioned technologies, an electrocatalyst is required to improve reaction dynamics and reduce barriers .…”

Currently, the oxygen evolution reaction (OER) plays a key role in the industrial application of renewable electrochemical technologies. Thus, developing electrocatalysts with high performance and sufficient stability for the OER is urgently pursued. Although perovskite oxides have provided numerous degrees of freedom for enhancing the electrocatalytic activity due to their diversity and flexibility, their investigation for the OER is mostly limited to pseudocubic structures. In this study, a complex perovskite oxide, Ba0.9Sr0.1Co0.8Fe0.1Ir0.1O3−δ (BSCFI-91), with a six-layer hexagonal (6H) structure, is synthesized first, displaying higher OER activity. Based on parent Ba0.9Sr0.1Co0.8Fe0.2O3−δ (BSCF-91), BSCFI-91 is obtained by replacing iron (Fe) with low-level iridium (Ir) doping and produces a current density of 10 mA cm–2 at a low overpotential of 300 mV, a small Tafel slope of 61.2 mV dec–1, and good stability up to 10 h in a 1.0 M KOH electrolyte. The dramatically enhanced OER performance is achieved by optimizing cobalt (Co) valence and highly oxidative oxygen species based on the hexagonal structure. The Ir incorporation facilitated the oxygen (O) p band center approaching to the Fermi level, indicating that BSCFI-91 could be a candidate in the electrocatalyst application. Moreover, this study opens up a new way to design efficient perovskite oxides for OER catalysis in terms of hexagonal crystal structures and composition modulation strategy.
