Abstract
The La0.8Sr0.2MnO3 nanocubes have been synthesized by simple precipitation followed by hydrothermal process. The as-obtained nanocubes were characterized by SEM, TEM, EDS, XRD and ICP-AA. The SEM and TEM images clearly showed cube type morphology of reaction product. The XRD pattern gave evidence for the phase purity and high crystallinity of the La0.8Sr0.2MnO3 nanocubes. The ICP-AA analysis along with EDS confirms the stoichiometry of the product. Electrochemical activity for oxygen reduction reaction was carried out in 1 M KOH. The oxygen reduction current measured by cyclic voltametry showed six times higher value for nanocubes than that of bulk catalysts of same composition.
