Oxygen reduction reaction activities of (LaMnO3)2/(SrMnO3). a Tafel plot of the oxygen reduction reaction (ORR) of (LaMnO3)2/(SrMnO3) in 0.1 M KOH. Error bars represent standard deviations of three independent measurements using three pieces of films deposited under the same condition. b A comparison of the ORR activities of (LaMnO3)2/(SrMnO3) at 0.8 V vs. reversible hydrogen electrode (RHE). LaMnO3-LaMnO3-LaMnO3 is referred to as “LLL”, LaMnO3-LaMnO3-SrMnO3 as “LLS”, LaMnO3-SrMnO3-LaMnO3 as “LSL”, and SrMnO3-LaMnO3-LaMnO3 as “SLL”
