Nanocrystalline LaSrMnO (LSMO) perovskite-sized powders were successfully synthesized at heating low temperature and time using the Pechini method based on polyesterification between citric acid and ethylene glycol. The electroactivity of carbon-supported perovskite (LSMO/C) for the oxygen reduction reaction (ORR) was evaluated. The results showed that the electroactivity of LSMO /C largely depends on the calcination temperature, type of electrolyte, and mass loading. It increased remarkably with the calcination temperature in 0.1 M KOH. The ORR performance was examined in KOH, NaOH, and KSO. Higher electroactivity was recorded in KOH electrolyte, as compared to NaOH and KSO. [ABSTRACT FROM AUTHOR] |
