CO2 High-Temperature Electrolysis Technology Toward Carbon Neutralization in the Chemical Industry

Solid Electrolytes for Low-Temperature Carbon Dioxide Valorization: A Review

“…Generally, the scaling-up process can encounter several issues, such as uneven distribution of electrode potential, gradient of relative humidity, and reduced CO 2 concentration along the flow channel . To address these challenges and unlock the full potential for practical applications, it is crucial to incorporate fundamental knowledge into the technological development for practical CO 2 valorization. , …”

Electrochemical hydrogen production: sustainable hydrogen economy

“…162 This method is very useful for obtaining these gases but requires a high production cost (80% of the energy comes from electricity). 163 Some technical issues are also involved because of the high temperature, such as leakage of gas-tight components, the requirement of tough materials and its limited application. Moreover, this method has high operational and maintenance costs.…”

Electronic engineering and oxygen vacancy modification of La0.6Sr0.4FeO3−δ perovskite oxide by low-electronegativity sodium substitution for efficient CO2/CO fueled reversible solid oxide cells

“…1–4 In this situation, reversible solid oxide cells (RSOCs) have emerged owing to favourable thermodynamics and kinetics of CO 2 conversion at high temperatures and reversible operational modes on the same device. 5–8 RSOC construction is generally composed of three sections: the air electrode which is exposed to the air-occurring for oxygen evolution reaction (OER) or the oxygen reduction reaction (ORR), the electrolyte, an oxygen ion conduction medium with almost no electronic conductivity, separating the air electrode and fuel electrode, and the fuel electrode where the crucial CO 2 /CO redox reactions take place. 9–12 It is well known that CO 2 molecules have a strong CO chemical bond, 13–15 which increases the difficulty of electrolyzing CO 2 , resulting in that the RSOC performance is mainly determined by the fuel electrode.…”
