dc.description.abstract | La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF), a perovskite material, is widely recognized as an excellent catalyst for the oxygen evolution reaction (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 to LSCF resulted in improved OER performance, comparable to that of commercial noble catalysts. Furthermore, we confirmed that fluorine-doped LSCF enhanced the oxygen reduction reaction (ORR) performance, establishing its effectiveness as a bifunctional catalyst. Moreover, when utilized as an air electrode in a homemade zinc-air battery cell, the electrochemical performance of the doped LSCF remained stable after repeated charge/discharge tests. These findings underscore the potential application of anion doping in electrochemical devices. | - |
