Appropriate electrolyte components and robust design of separators are the necessary components of the LSB pouch cells that significantly affect the cycling life and electrochemical performance.

CO<sub>2</sub> reducing electrodes (cathodes) form the central challenge in enabling solid oxide technology for CO<sub>2</sub> electrolysis. Typical cathodes can comprise of both oxides such as perovskites and metals such as Ni and Fe. Efforts at improving the activity, selectivity, and stability of the electrodes continue. Operando methods provide direct access to active sites during the reaction and provide valuable information such as the identity of catalytic material, nature of reaction intermediates, oxidation state of catalytic ions, etc. These methods have created a deeper mechanistic understanding, unravelled new performance indicators, and increasingly enabling a deep diagnostic based systematic development of catalysts and processes. This study summarises and analyses data from operando approaches to develop an understanding of CO<sub>2</sub> reduction mechanism on certain commonly studied electrodes. In particular, this review discusses CO<sub>2</sub> reduction mechanism on electrodes such as Ni-YSZ, CeO<sub>2-x</sub> and perovskites such as La<sub>1-x</sub>Sr<sub>x</sub>FeO<sub>y</sub>. The CO<sub>2</sub> reduction on these surfaces essentially progresses on an oxide terminated surface via formation of a three coordinated carbon (carbonate type) intermediate formed at oxygen defect sites. Metal electrodes such as Ni-YSZ were found to oxidize in situ in presence of CO<sub>2</sub> and the reaction proceeded via oxide mediated mechanism. In electrodes such as La<sub>1-x</sub> Sr<sub>x</sub>FeO<sub>y</sub>, exsolution of metals was essentially found to have no direct impact on CO<sub>2</sub> electrolysis. In the context of catalyst coking on CeO<sub>x</sub> electrodes, new descriptors, such as the number of reduced sites (Ce<sup>3+</sup>), and the existence of metal carbonyl species “Ce<sup>3+</sup> – CO” have emerged.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"46 ","pages":"Article 101514"},"PeriodicalIF":8.5,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140770337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
