Understanding CO2 electrochemical reduction kinetics of mixed-conducting cathodes by the electrical conductivity relaxation method

Enhanced CO2electrolysis through modulation of oxygen vacancies

“…This provides us with new ideas for future research. [50][51][52] In addition, it can be found that the performance of CO 2 to CO conversion of LSF is slightly decreased relative to that of LSC 0.25 F 0.75 . This phenomenon is well explained by the information provided in Table 1.…”

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

“…2d) because of higher relative mass loss at higher temperatures from 700 °C to 850 °C. The LSF is a P-type conductor under an air/CO 2 atmosphere, and the oxygen vacancy and hole charge carrier will form based on the following eqn (9): 57 …”

Enhancing CO2 Catalytic Adsorption on an Fe Nanoparticle-Decorated LaSrFeO4 + δ Cathode for CO2 Electrolysis

“…The ECR method is a robust technology to evaluate the catalytic activity of electrode materials for CO 2 reduction and has received considerable interest in CO 2 or H 2 O electrolysis. ,,− The conversion of CO 2 to CO can be expressed by the following eq where Fe Fe ′ , Fe Fe x , V O .. , and O O x represent Fe 2+ , Fe 3+ , oxygen vacancies, and lattice oxygen in cathode oxides, respectively.…”
