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

Abstract The electrocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) provides a feasible approach for the efficient utilization biomass. Defect regulation is an effective strategy in field biomass upgrading to enhance adsorption capacity reactants and thus increase activity. However, how select appropriate strategies regulate over‐enrichment induced by excessive oxygen vacancy still huge challenge. In this work, defect‐filling design construct element‐filled site layered double hydroxide (S─Ov─LDH) adopted, which achieves significant reduction electrolysis potential platform molecule HMF reaction current density. Physical characterizations, electrochemical measurements, theoretical calculations prove that formation metal─S bond second shell effectively regulates electronic structure material, weakening over‐strong OH − vacancy, promoting high‐valence Co 3+ during reaction, forming new sites. This work discusses catalytic enhancement mechanism defect filling detail, fills gap upgrading, favorable guidance further development strategies.
