Oxygen reduction reaction activity and structure of La-based perovskite oxides

1706 files in 35 folders, containing 388MB. Comprises plots, figures, and manuscripts. The data contains x-ray diffraction patterns and electrochemical data of lanthanum based perovskite oxides (e.g. 9 different perovskite compositions e.g. LaNiO₃, LaCoO₃, LaFeO₃, LaMnO₃, LaCrO₃, LaNi_0.5Co_0.5O₃ and LaNi_0.5Fe_0.5O₃, LaNi_0.5Mn_0.5O₃ and LaNi_0.5Cr_0.5O₃) characterized using rotating ring disk electrodes.
