Oxygen evolution behavior of La1−xSrxFeO3−δ electrodes in LiCl–KCl melt

Abstract Electrochemical reduction processes of oxides in molten salt have been proposed as the carbon-free technologies order to achieve carbon neutrality. The anodic behavior La 1 −x Sr x FeO 3− δ an O 2 evolution anode LiCl–KCl at 723 K was investigated. results suggested that K, electrical conductivity 3 −δ tended increase with doping. reactions 1− electrodes were characterized by electrochemical measurements + Li K. Based on cyclic voltammograms 0.7 0.3 electrode, has proceeded between 2.7 and 3.6 V. potential electrode during galvanostatic electrolysis conducted 39 mA cm −2 for 15 h remained stable 2.8 V, indicating gas monitored. corrosion rate estimated low value 8.6 × 10 −4 g −1 . Electrode surface data obtained after indicated exhibited excellent chemical physical stability This indicates is promising candidate material inert anodes oxide decomposition. As application electrolytic CO also successfully achieved. Graphical
