La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF), a perovskite material, is widely recognized as an excellent catalyst for the oxygen evolutionreaction (OER). An anion doping strategy was implemented to enhance the presence of highly oxidation-active O2−/O− species crucial for the electrochemical reaction, effectively replacing oxygen. The introduction of 5 mol% fluorine toLSCF resulted in improved OER performance, comparable to that of commercial noble catalysts. Furthermore, we confirmedthat fluorine-doped LSCF enhanced the oxygen reduction reaction (ORR) performance, establishing its effectiveness as abifunctional catalyst. Moreover, when utilized as an air electrode in a homemade zinc-air battery cell, the electrochemicalperformance of the doped LSCF remained stable after repeated charge/discharge tests. These findings underscore the potentialapplication of anion doping in electrochemical devices.
