Effect of Calcination Temperature on the Electrocatalytic Properties of La0.6Sr0.4CoO_3 AITranslate
Abstract AITranslate
La0.6Sr0.4CoO3 perovskite-type oxide was prepared with sol-gel method, and the effect of calcina- tion temperature on its electrocatalytic properities in bifunctional oxygen electrodes was particularly stud- ied. The phase and morphology of La0.6Sr0.4CoO3 perovskite-type oxide were analyzed by XRD, SEM and BET,and the steady-state polarization curves and steady-state galvanostatic curves of the cathode and an- ode of the bifunctional oxygen electrodes were plotted in a three-electrode system. The results show that increasing the calcination temperature is advantageous for decreasing the impurities in La0.6Sr0.4CoO3 per- ovskite-type oxide. When the calcination temperature reaches 800 ℃, pure La0.6Sr0.4CoO3 perovskite-type oxide is obtained with the highest catalytic activity,and the bifunctional oxygen electrode owns the lowest electrochemical polarization and the highest stability.
